3 Overview Welcome to the Structure Preliminary Layout User's Guide. This guide is intended for users who need to become quickly familiar with the Structure Preliminary Layout Version 5 product. This overview provides the following information: Structure Preliminary Layout in a nutshell Before reading this guide Getting the most out of this guide Accessing sample documents Conventions used in this guide Structure Preliminary Layout in a Nutshell Version 5 Structure Preliminary Layout allows you to model the early definition of hull forms, major ship zones and main structures. It offers an easy-to-use and easy-to-learn graphic interface. The overall ship design project goes through a number of different phases from conceptual design through functional and detail design to extraction of deliverables. This product addresses initial design requirements for the shipbuilding industry. It focuses on internal arrangement and definition, including major bulkheads and decks, on subdivision into compartments of simple and complex shapes, and lets you compute data used in hydrostatic analyses. Other outputs include lines drawings, project data in IDF format and offset data in XML format. This early definition of the ship will then be further refined during the functional and detail design phases.

4 As a scalable product, Structure Preliminary Layout can be used with other Version 5 products such as Generative Drafting 2 (GRD) and Generative Shape Design 2 (GSD). Before Reading this Guide Before reading this guide, you should be familiar with basic Version 5 concepts such as document windows, standard and view toolbars. We therefore recommend that you read the Infrastructure User's Guide that describes generic capabilities common to all Version 5 products. You may also like to read the following complementary product guides, for which the appropriate license is required: Generative Drafting User's Guide Generative Shape Design User's Guide.

27 4. Click OK when done.

28 Saving Documents This task contains recommendations on saving your documents. Ways in which documents are saved are explained in the Infrastructure User's Guide - Creating, Opening and Saving Documents. You must read that documentation because the various methods are not explained here. This task simply suggests the methodology you should follow in specific circumstances. 1. If you are saving a document to a local machine or network drive it is recommended that you use the "Save Management" command initially. The Propagate Directory command (which is in the Save Management dialog box) should not be used routinely. It is meant to be used in specific circumstances, such as when you want to place all the contents of a document in one directory before sending it to another location. 2. If you are saving a document to another site or network you should use the "Send To" command. In this case, you should be careful about the links for documents such as resolved parts folder or line ID. These links could change to reflect the local network drive to which the documents have been sent. You should make sure they point to the original location - using the Reset button in the Save Management dialog box is one way of doing this. 3. You should check the active document before you execute the Save command. The root product must be the active document if you want to save everything under it.

29 User Tasks The tasks you will perform in the Structure Preliminary Layout workbench are related to the general definition of the ship, including hull shape, main decks and bulkheads as well as general layout. Resources & Default Settings Don't forget to set your options correctly before starting to work (Tools -> Options..., Equipment & Systems, Structure Preliminary Layout). Before you begin, customize standard views to shipbuilding conventions. Browsing Project Data Wrapping Surfaces Molded Forms Compartments Boundaries Openings Exporting Data in IDF Format Generating Offset Data Object Relationships Creating Reports Producing Lines Drawings Creating Plane Systems Managing Your Project Structure Preliminary Layout Package in Knowledge Expert

30 Browsing Project Data Defining the project is an administrator's task and is managed as a project resource. Doing so: Gives the project a name Specifies conventions for main ship directions Specifies conventions for hull form orientations Specifies the overall dimensions of your project. You can browse project data using the Edit Project command. This task shows you how to browse project data. 1. Click the Edit Project icon. The Project Edition dialog box appears. The Project Id field specifies the name given to the project. 2. Click Naming Conventions... to access other project data. The dialog box expands showing adopted conventions for main ship directions (Coordinate System tab) and hull form orientations (Hull Form tab). Ship directions are defined with respect to the coordinate system of the document. 3. Click the Hull Form tab.

31 4. Click the Bounding Box tab. Bounding Box The bounding box specifies the overall project dimensions as defined by the administrator. A set of default dimensions are supplied with the product. The center of the box is positioned at the center of the document. You may need to click the Fit All In bounding box. command to visualize the When you create the wrapping surface, the bounding box is automatically re-dimensioned to include the hull form. If features are created outside the bounding box, consult to the administrator. 5. Click OK when done.

32 Wrapping Surfaces About wrapping surfaces Prepare imported surfaces: open the surface, then use Generative Shape Design to orient, analyze and perform necessary operations Create hull forms: add the wrapping surface feature, import the surface and associate the surface to the feature Create deckhouses: create the deckhouse from scratch using Generative Shape Design, then associate it to the wrapping surface feature Use basic wrapping surfaces for complex hull forms: split the imported surface using Generative Shape Design then associate split surfaces to the wrapping surface feature Modify wrapping surfaces: edit the wrapping surface feature and change specifications in the dialog box that appears. Replace wrapping surfaces: import the replacement surface, switch to Generative Shape Design and use the Replace contextual menu command. Calculate general hull characteristics and form coefficients: edit the wrapping surface feature, select the Form Coefficients tab, specify the draft location and click Calculations.

33 About Wrapping Surfaces Wrapping surfaces are used to define the hull forms (internal and external) and deckhouse. In the case of hull forms, surfaces are usually imported, whereas for deckhouses they are created from scratch. The wrapping surface can be a single surface or can be made of several surfaces to take into account special cases such as illustrated below. The wrapping surface is an object class managed in the feature dictionary. Note: Shell expansion tools in Structure Functional Design work on hull form halves (portside and starboard wrapping surfaces) or a section of the hull form and not the complete hull form. The transom must be considered a bulkhead and not an integral part of the hull. Managing Wrapping Surface Type You can manage wrapping surface type via the feature dictionary or directly in the Structure Preliminary Layout workbench via the Type attribute. To do so via the Type attribute: Right-click the wrapping surface feature in the specification tree and select the Properties command. The Properties dialog box appears. Click the Conceptual Structure tab. Enter the type, deckhouse for example. Click OK in the Properties dialog box. Object naming rules based on type can also be defined to identify objects in your document. Bounding Box When you create the wrapping surface, the bounding box defining overall project dimensions is automatically redimensioned to include the hull form and deckhouse. The bounding box is managed by the administrator as a project resource. To visualize the bounding box, browse the project data using the Edit Project command.

34 Publishing Wrapping surfaces you define are automatically published. This is identified by a Publication entry in the specification tree with one publication feature for each wrapping surface published. If several basic wrapping surfaces are defined, the complete wrapping surface is the result of merging all constituent wrapping surfaces. Molded forms and compartments you create will reference the published surfaces (identified by their publication name) and not the underlying surfaces. This lets you replace the hull form or deckhouse at any time without affecting any downstream work. Do not change publication names of surfaces referenced by molded forms and compartments: links between the two will be lost.

35 Preparing Imported Surfaces Imported surfaces are generally used to define wrapping surfaces for the hull (internal and external forms). Before doing so, these surfaces have to be properly positioned in the coordinate system of the document and optimized to obtain a coherent surface. You can import IGES files, idf type and CATPart documents. This task shows you how to open, then position and optimize surfaces. Opening Existing Surfaces 1. Click the Open icon or select the File->Open... command. The File Selection dialog box appears. 2. In the File Selection box, select the file location. 3. In the Files of type drop-down list, select the document type you want to open: CATPart idf igs (IGES file) 4. Click Open. You are now ready to position and optimize your surface. This is done in the Generative Shape Design workbench. Positioning & Optimizing Surfaces 5. Change to the Generative Shape Design workbench (Start -> Shape -> Generative Shape Design). You will begin by positioning the surface in the coordinate system of the document. Doing so defines the main ship directions. When you copy your surface into the ship project, it will be positioned in the same way. 6. Click the Create Datum icon (Tools toolbar) to deactivate the history mode: When you create elements, there are no links to the entities used to create them. 7. Orient the surface using Translate, Rotate, Symmetry and Scaling commands (Insert -> Operations). You can now analyze your surface and perform necessary operations to obtain a coherent surface.

36 8. Analyze your surface using Analysis commands (Insert -> Analysis) to determine whether healing, joining, etc. is necessary. 9. Perform necessary operations, for example, healing to fill gaps between surfaces (Heal command), joining to join surfaces (Join command). These commands are found in the Insert menu (Insert -> Operations) or in the Operations toolbar. For more information on these tasks, see the appropriate sections in the Generative Shape Design User's Guide. You are now ready to import your surface into Structure Preliminary Layout to create a wrapping surface.

37 Creating Hull Forms This task shows you how to create a single wrapping surface for the hull form from an imported surface. In this task, you will: add the wrapping surface feature import the surface into the Structure Preliminary Layout workbench edit the wrapping surface feature to associate the imported surface to the wrapping surface feature and orient the surface properly. Deckhouses are generally not imported surfaces, but are created from scratch. Adding the Wrapping Surface Feature 1. Click the Wrapping Surface icon. The Wrapping Surface Class Definition dialog box appears. The wrapping surface is created under the active product or assembly. 2. Click Change... opposite Object class to change the wrapping surface class. The Class Browser opens and accesses the feature dictionary defining object classes. A sample dictionary is supplied with the product.

38 3. Click the Expand tree icon in the Class Browser to view available classes. 4. Select the class, then click OK. The selected class is identified in the Wrapping Surface Class Definition dialog box.

39 5. Click OK in the Wrapping Surface Class Definition dialog box to define the wrapping surface feature: The feature is added to the specification tree. You are now ready to import the surface. Importing the Surface You can import IGES files, IDF type and CATPart documents. Surfaces must first be prepared, i.e. properly positioned and optimized. 6. Open the document containing the surface to be imported. 7. Copy the prepared surface (last feature in the specification tree). 8. Paste the surface into the Structure Preliminary Layout document using the Paste Special... command, As Result option. Using the As Result option, means that the geometry only (not specifications) is copied. No feature history is kept.

40 You can paste the surface at reference part level or directly under the Wrapping Surface Geometry. If you paste it directly under the Wrapping Surface Geometry, you must activate the reference part first. The copied surface is pasted under Wrapping Surface Geometry. Note: The bounding box is automatically re-dimensioned to accommodate the hull form.

41 If you need to create more than one wrapping surface, import the surface into Structure Preliminary Layout then split it into the number of required basic wrapping surfaces before associating basic surfaces to the wrapping surface feature. In this way, you keep the associativity between the imported surface and the basic wrapping surfaces. This allows easy replacement of the imported surface: you simply need to replay the split features. 9. If necessary, update your document. Associating the Surface to the Wrapping Surface Feature 10. Edit the wrapping surface feature: The Wrapping Surface dialog box appears. 11. Select the surface just pasted. Publication Name Wrapping surfaces are identified by their publication names in the Molded Form and Compartment commands. You can change publication names when you create surfaces but must not do so after they are referenced by molded forms or compartments.

42 12. Define the default setting for the selected surface: Yes: considers the surface as a default surface. This surface is automatically proposed when performing other operations, such as creating molded forms. No: the selected surface is not considered a default surface. Double-click to set the surface to No. 13. Check wrapping surface orientation and if incorrect, click the orientation vector in the geometry area or select Switch Orientation Name in the dialog box. Naming is that defined for the project. 14. Click OK when done: The wrapping surface has been created and published.

43 Creating Deckhouses Wrapping surfaces for deckhouses are generally created from scratch. This is done using the Generative Shape Design workbench directly in the Structure Preliminary Layout document. This task shows you how to create wrapping surfaces from scratch. Adding the Wrapping Surface Feature 1. Click the Wrapping Surface icon. The Wrapping Surface Class Definition dialog box appears. The wrapping surface is created under the active product or assembly. 2. Click Change... opposite Object class to change the wrapping surface class. The Class Browser opens and accesses the feature dictionary defining object classes. A sample dictionary is supplied with the product.

44 3. Click the Expand tree available classes. icon in the Class Browser to view 4. Select the class, then click OK. The selected class is identified in the Wrapping Surface Class Definition dialog box. 5. Click OK in the Wrapping Surface Class Definition dialog box to define the wrapping surface feature: The feature is added to the specification tree. You are now ready to create your surface from scratch. Creating the Surface from Scratch 6. Expand the specification tree and double click Wrapping Surface Geometry: The workbench changes to Generative Shape Design. 7. Create a surface. This is done by: Sketching necessary wireframe geometry using the Sketcher Creating the surface. Use existing features in the document to position your surface correctly first time. Two alternative sketches are proposed in this scenario. A. From two closed profiles: Resulting surface using the Loft command:

45 B. Extrude two profiles (Extrude command) Trim ( ) extruded surfaces to obtain resulting surface: For more information on creating surfaces, see the appropriate section in the Generative Shape Design User's Guide. Associating the Surface to the Feature 8. Edit the wrapping surface feature using the contextual menu: The Wrapping Surface dialog box appears. 9. Select the surface just created. If the entire surface is not highlighted in the geometry area, your selection is not correct. Select the surface in the specification tree. Publication Name Wrapping surfaces are identified by their publication names in the Molded Form and Compartment commands. You can change publication names when you create surfaces but must not do so after they are referenced by molded forms or compartments.

46 10. Define the default setting for the selected surface: Yes: considers the surface as a default surface. This surface is automatically proposed when performing other operations, such as creating molded forms. No: the selected surface is not considered a default surface. Double-click the surface in the dialog box to change Set as Default to No. 11. Check wrapping surface orientation and if incorrect, click the orientation vector in the geometry area or select Switch orientation name in the dialog box. Naming is that defined for the project. 12. Click OK when done: The wrapping surface has been created and published.

47 Creating Complex Hull Forms The wrapping surface defining the hull form can made of more than one basic surface. This is useful when molded forms are trimmed to complex hull forms. To do so, split the imported surface in the Structure Preliminary Layout document. This keeps the associativity between the imported surface and the component surfaces you create, and allows easy replacement of the imported surface - you simply need to replay the split features. When you have done this, associate all split surfaces to the wrapping surface feature. This task shows you how to split hull forms and create basic wrapping surfaces. Have imported a surface and created the wrapping surface feature. Splitting the Imported Surface 1. Double-click Wrapping Surface Geometry in the specification tree to change to the Generative Shape Design workbench. Note: You remain in the Structure Preliminary Layout document. 2. Using the Split icon and reference planes, create as many surfaces as needed. Don't forget to check Keep both sides in the Split Definition dialog box. How reference planes intersect the imported surface is important: only one intersection must be made. The plane intersects the surface twice. This case cannot be resolved.

48 Examples below show ways to split the complex imported surface using two reference planes. Two separate surfaces are created. A basic wrapping surface is then defined for each surface. Defining Basic Wrapping Surfaces 3. Edit the wrapping surface feature: The Wrapping Surface dialog box appears. 4. Select the surfaces just created.

49 Complete Wrapping Surface Name If several basic wrapping surfaces are created, the complete wrapping surface (the result of merging basic wrapping surfaces) is identified by the name given in Name field. You can change this name before you publish wrapping surfaces but not after. If the wrapping surface corresponds to only one surface, it is identified by its publication name. Publication Name Wrapping surfaces are identified by their publication names in the Molded Form and Compartment commands. You can change publication names when you create surfaces but must not do so after they are referenced by molded forms or compartments. 5. Define the default setting for component surfaces: Yes: considers the surface as a default surface. This surface is automatically proposed when performing other operations, such as creating molded forms. No: the surface is not considered a default surface. Double-click the surface in the dialog box to change Set as Default to No. 6. Check the orientation of the complete wrapping surface and if incorrect, click the orientation vector in the geometry area or click Switch Orientation Name in the dialog box. Naming is that defined for the project. 7. Click OK to create and publish wrapping surfaces. When the wrapping surface is made of several basic surfaces, a complete surface (merging all basic wrapping surfaces) and all constituent surfaces are published. Publishing individual surfaces is particularly useful if hull forms need to be replaced.

50 Modifying Wrapping Surfaces This task shows you how to edit wrapping surfaces. 1. Edit the wrapping surface feature of interest. The Wrapping Surface Definition dialog box appears showing wrapping surface specifications. You can: Change wrapping surface orientation Remove and/or add basic wrapping surfaces Change the Set as default setting for basic wrapping surfaces. 2. To change wrapping surface orientation, click Switch Orientation Name or click one of the orientation vectors in the geometry area. Naming is that defined for the project. 3. To remove a basic wrapping surface, select the surface in the dialog box, then click Remove. 4. To add a basic wrapping surface, simply select the surface you want to add.

51 5. To change the Set as default setting, double-click the surface whose setting you want to change. Yes: considers the surface as a default surface. This surface is automatically proposed when performing other operations, such as creating molded forms. No: the surface is not considered a default surface. 6. Click OK when done.

52 Replacing Wrapping Surfaces This task shows you how to replace wrapping surfaces. 1. Import the surface you want to use to replace an existing wrapping surface: Copy the surface Paste it at reference part level or directly under the Wrapping Surface Geometry using the Paste Special... command, As Result option. 2. Edit the wrapping surface feature. The Wrapping Surface Definition dialog box appears. 3. Select the surface you want to replace (Surface.1) then click Replace. Note: If you worked on the original surface using the Generative Shape Design workbench, using for example scaling or applying symmetry, then a dialog box appears asking which surface (the original surface or the worked surface) you want to replace. 4. Select the surface you imported (Surface.2) that will replace the existing surface.

53 5. Click OK when done. The surface has been replaced and the wrapping surface feature rebuilt. If you created other preliminary layout entities that reference the wrapping surface, you will have to update your document to rebuild these features. Entities requiring an update are highlighted in the document and identified as such in the specification tree.

54 Calculating General Hull Characteristics and Form Coefficients This task shows you how to compute general characteristics of the hull as well as form coefficients. This data is used in hydrostatic calculations. 1. Edit the wrapping surface feature. The Wrapping Surface Definition dialog box appears. 2. Select the Form Coefficients tab. 3. Specify the location of the draft: enter a value in the Draft box. 4. Click Calculations to compute general hull characteristics and form coefficients.

55 Main characteristics Length (Lwl) Breadth (Bwl) Length between perpendiculars; length at waterline Breadth at waterline Displacement Wetted surface Water plane inertia LCB VCB TCB Longitudinal position of center of buoyancy Vertical position of center of buoyancy Transverse position of center of buoyancy Form coefficients Cb Cwp Cp Cm Block coefficient Water plane coefficient Prismatic coefficient Midship section coefficient 5. Click OK when done.

56 Molded Forms About molded forms Create simple molded forms: Define the class, select the reference element then the limits and adjust to create on right side Create multiple molded forms: Select the reference molded form then all reference planes at which to create molded forms Create external molded forms: Define the class, create the geometry using Generative Shape Design then associate the geometry to the feature Modify molded forms: Edit the molded form (contextual menu) and modify specifications as desired

57 About Molded Forms Molded forms are surfaces used to divide the ship into main volumetric regions or compartments. Typical molded forms are transverse and longitudinal bulkheads, and decks. Structure Preliminary Layout provides tools letting you create simple molded forms based on a reference plane and bounded by the hull form, planes or other molded forms as well as multiple molded forms based on the selection of a set of reference planes. Reference planes are created in a new part using the Generative Shape Design workbench. For more complex molded forms, an external molded form command lets you can associate your own geometry created using Generative Shape Design to a molded form. Molded forms have an orientation represented by a combination of two vectors. The default orientation for decks is top/bottom, for example. The molded form is an object class managed in the feature dictionary. Publishing Molded forms you define are automatically published. This is identified by a Publication entry in the specification tree. If your molded forms contain openings, two publication features are published, one for the surface without the opening and the other for the surface with the opening.

109 Object Relationships This feature aids the designer in identifying and viewing generic relationships between objects, and is particularly useful for viewing relationships between objects coming from different applications. The different types of relationship are organized under tab pages: Assembly: shows the product structure tree (parent/children) relationships Groups: shows group/member relationships of logical groupings of objects, such as piping lines and piping spools. Limits: shows objects geometrically limiting the current object. Connections: shows objects connected to the current object. Interference: shows objects interfering with the current object. This is useful for detecting objects that require attention or redesign. Penetration: shows objects involved in a penetration relationship (stored in ENOVIA) with the current object. This tab is only available when the document is opened from ENOVIA. The tab pages available and the relationships shown in each tab page are controlled by the object selected (the current object). This tasks shows you how to use the Object Relationships command. To reduce unnecessary computer processing time when viewing object relations in the Interference tab you will need to make some changes in the Tools -> Options settings. Go to Tools -> Options, select Digital Mockup, DMU Space Analysis then click the DMU Clash - Detailed Computation tab.

The Reframe Main Window button updates the geometry area with the preview viewpoint.

111 2.Double-click an object to view its relationships. The various tabs will become active only when the selected object supports that kind of relationship, for example, if it is a type of object that can have limits. In the example below, a deck has been selected to view Limits. In the Visualize column, toggle the Y/N to show or hide an object in the preview pane.

112 An object can be selected from the geometry area, the specifications tree, or from the assembly tree or via the preview pane in the dialog box. In any tab page: Select an object to highlight it. Double-click to view the tree structure. Right-click to access the contextual menu and display properties or hide / show the object. Use Previous Object and Next Object buttons to revisit the history of objects and tab pages viewed since the command was started. 3.Click the Interference tab to display objects that clash (intersect) with the current object. You can filter the list by selecting All Type, Contact or Clash. Note: Only basic geometric objects, not assemblies, can be analyzed for interferences. Select the Hide connected objects check box to hide objects with known connections (i.e. listed in the Connections tab) and not display them in the Interference tab list. 4.Click the Connections tab to display connected objects. Take some time to experiment with the several combinations of tab selection, object type and filter selections and observe the available information. 5.Click Close when done.

113 Creating Reports You can generate reports that get the values of properties of objects in your documents. To do so, you must first define the report format which identifies which properties you are interested in. This report format is then used to generate reports. This task shows you how to create a report. 1. To be able to use this function, load the required knowledgeware package: Select Tools -> Options, General -> Parameters and Measure Click the Knowledge tab Check the load extended language libraries option Load the Structure Preliminary Layout package. 2. Define the report format identifying which properties you are interested in. Use Edit -> Search to select the objects for which you want to obtain a report. For more information on searching using the General, Favorites and Advanced modes, see the Infrastructure User's Guide. The 'Or' option in the Advanced mode is particularly useful for combining search criteria to select objects. 3. Generate your report based on the report format you defined. Important: Select the Currently Selected Objects option in the Generate a report dialog box. Typical Structure Preliminary Layout report:

114

115 Defining the Report Format You use this function, together with the function described in Generating a Report, to get the values of properties of objects in a document. This task shows you how to define the report format. Examples from the Piping workbench are used here. Substitute the appropriate resource or directory when working in another workbench. Before you generate a report you need to define its format. This means deciding which properties you are interested in. This report format is kept in a file which you can use to generate reports from other documents. It is recommended that you use queries, as explained below, if you will be modifying a document and running a report on it repeatedly. If you do not use a query the report may not update after you modify a document. To use this function you must first make sure of a setting. Click Tools - Options - General - Parameters and Measure and click on the Language tab. Under Language check Load extended language libraries. Either check All Packages, or uncheck this option and load the packages you will be using. 1. Click Tools - Report - Define. The Report Definition dialog box displays.

116 You can toggle between Yes and No for the Column headings Sort, GroupBy and Sum. A blank means No. To toggle click beneath the column heading. In the example above, for the attribute Name, Sort is No, Group By is Yes and Sum is No. 2. The report name field is informative. You can use the button next to it to open an existing report. You will need to enter a report name and location when you click the Save As button. Enter a report title - you can enter anything but you must have a title. 3. Check the Show Inherited Attributes box if you want to.

117 4. Click on the down arrow and select the dictionary related to your program. In this case the EquipLayout package has been selected. See Using Knowledgeware Packages for more information. 5. Select the type of object. The list of attributes you will see in Step 6 will depend on the type you select here. However, when you generate a report you will get values for all objects in the document that have the attributes included in your report format. If you want to limit the objects for which you get a report you must create a query (Step 8). 6. Select an attribute in the Attribute field and click the Add button. The attribute will be added in the window. Add as many attributes as you want to. 7. Select Yes or No for the column headings. Sort: You only Sort by one of the attributes - if you select Name the report will sort in alphabetical order. GroupBy: If you select Yes for one of the attributes, the report will group objects by that attribute. Sum: For dimensional attributes like length. If you select Yes the report will sum up the attribute you selected. For 3D applications it can compute dimensions like length from the document. You must select the correct option in the Generate a Report dialog box - you may need to select the objects and choose the 'currently selected objects' option. For 2D applications attributes must have values defined. Quantity: If you select the Quantity checkbox and the Group By column heading, a Quantity field will be added to the report. It will display a number, which shows how many parts that attribute is common to. For instance, if you group by class name and select the quantity checkbox, the report will show how many objects with the same class name exist in your document. 8. You can further refine your report by using the Edit - Search function to define a query. This will allow you to generate a report on a narrower selection of check valve, say, of a certain size, instead of all check valves in your document. The queries you create will be available for selection when you click the arrow in the Query Name field above. Detailed instructions on using the Search function can be found in the Infrastructure User Guide under Basic Tasks - Selecting Objects. Briefly, click Edit - Search to bring up the Search dialog box. Select the Advanced tab, then select a workbench, type of object and attribute you are interested in. Clicking the Add to Favorites button brings up the Create a Favorite Query dialog box, where you can name the query and save it.

118 Generating a Report This task explains how to generate a report listing values of selected properties. Before you do this you need to define the report format. Examples from the Piping Design workbench are used here. Substitute the appropriate resource or directory when working in another workbench. 1. Click Tools - Report - Generate. The Generate Report dialog box displays. 2. Click the Open button and select the format you want to use for your report, in this case NewReport. 3. If you had defined a query in your report format then check Objects From Predefined Query. 4. If you select one or more objects in the document then check the option Currently Selected Objects. 5. Check All Objects in Document if you want a report on all objects in your document. 6. Click OK and select a format, such as HTML, when you are prompted. The report will be generated. It shows values for all properties defined in your report format for all objects in the document that have them. Where an object does not have a property the report displays asterisks.

119 7. Click Insert in Doc if you want to display these values in your document. To generate the report from a schematic and insert it in a schematic, click on the Insert in Doc button and click anywhere in your drawing. To generate the report from a 3-D document and insert it in a drafting document, click on the Insert in Doc button and select the sheet or view in the specifications tree. Do not select a point in the sheet. The XY Coord dialog box will pop up - enter the location where you want to insert the report. The data will be placed at the location. It can be moved to another location later by click and drag. 8. Click Save As to save the report. Specify a file name and location.

120 Producing Lines Drawings Three different views showing the shape of a ship can be generated: Waterlines view looking down on the ship from above. Body plan showing the shapes of the frame lines. Profile view looking into the ship from the side. This tasks shows you how to generate lines drawings. Have your 3D document opened. 1.Specify your settings before you start: Select Tools ->Options ->Equipment & Systems -> Structure Preliminary Layout then the Drafting tab. 2.In addition, you will need to set the following drafting options: In the Options dialog box, select Mechanical Design ->Drafting ->View Check Project 3D wireframe, Project 3D points and Apply 3D specifications. 3.In the Structure Preliminary Layout document, select all 3D geometry and any planes to be used to generate drawings before entering the Drafting workbench. Body Plans To completely close the body plan, you must create a boundary using the Boundary command in the Generative Shape Design workbench: Activate the wrapping surface Change to the Generative Shape Design workbench Click the Boundary icon Select the wrapping surface.

121 4.Create a new drawing: Select Start -> Mechanical Design -> Drafting. You switch to the Drafting workbench and the New Drawing Creation dialog box appears. Select the view you want to create. Click OK in the New Drawing Creation dialog box. 5. Click the Front View or Advanced Front View icon. The Advanced Front View command lets you enter a name and scale. The recommended scale is 1: Return to the 3D document and select a plane of a 3D part or a plane surface to define the projection plane and the drawing view. A 3D view is previewed on your drawing. Use the drafting manipulator to adjust the view. 7.Click inside the view to generate the view.

122 For more information on drafting capabilities, see the Drafting User's Guide.

123 Creating Plane Systems The Plane System command provides tools letting you define a number of planes in a given direction. Planes can then be used as reference planes or supports when creating other items. In structure applications, you can, for example, define reference planes in each ship direction to assist you place structural elements. You must define one plane system for each direction. This task shows you how to create a regular asymmetric, a irregular asymmetric and a semiregular plane system. 1. Click the Plane System icon. In the Generative Shape Design workbench, this icon is to be found in the Tools toolbar. You can also select Insert -> Advanced Replication Tools -> Plane System... In the Structure Preliminary Layout workbench, this icon is to be found in the Structure Grid Set toolbar. Having selected this command, you also need to select an entry in the specification tree under which you want to create a new CATPart to locate your plane system before proceeding. If you want to use an existing CATPart, then select that CATPart in the tree. For Structure Functional Design, switch to the Generative Shape Design workbench. The Plane System dialog box appears.

124 2. Select the type of plane system you want to create: Five types are available: Regular symmetric Regular asymmetric Semi-regular Irregular symmetric Irregular asymmetric. Symmetric Plane Systems Symmetric plane systems are created in similar fashion to asymmetric plane systems. The difference being that they have the same number of planes on either side of the origin. Creating a Regular Asymmetric Plane System 3. Select a plane or a line to define the direction of the plane system. If you select a plane, the center of the plane is automatically taken as the origin of the plane system and an arrow appears showing the direction. You can, if desired, change the origin.

125 4. If you selected a line, select a point to define the origin, Or, If you selected a plane and want to change the origin, click the Origin field and select a point. Use the Reverse button in the dialog box or select the arrow in the geometry area to invert the direction. The contextual menus in Direction and Origin fields let you create appropriate geometry directly without having to exit the current command. 5. Specify the primary subset: Specify the distance between two planes in the Spacing field. Enter a prefix identifying all planes in this set. Planes are identified by this prefix plus a positive or negative number that increments away from the origin. Plane numbers are positive in the direction of the plane system. The origin is identified by prefix.0. Specify the number of planes. The number you enter is the number of planes you want to create on either side of the origin. Note that the number of planes does not include the plane at the origin. 4. Optionally, check Allow secondary subset to group a number of planes in the primary subset together and create a secondary subset: Specify the step. For example, enter 4. Every fourth primary subset plane will belong to the secondary subset. Enter a prefix identifying all planes in this set.

126 Note: The plane at the origin always belongs to the primary subset. Select the subset in the specification tree to visualize all planes in this set in the geometry area. 6. Click OK when done to create a plane system along the specified direction. Creating an Irregular Asymmetric Plane System Plane systems can be created by importing a TSV (tab-separated) file containing the definition of the plane system. This file must be formatted as follows: positive_or_negative_absolute_distance_from_origin<tab>subset_prefix where <TAB> denotes a TAB character and should contain an entry 0<TAB>subset_prefix. Typically, WEB FRM FRM FRM WEB

127 ... 0 FRM WEB 2700 WEB Notes: Do not type space characters using the space bar. It is not necessary to specify the positive sign '+' when entering positive distances. It defines a plane system in one ship direction only but can contain as many subsets as desired. 3. Select a plane or a line to define the direction of the plane system. If you select a plane, the center of the plane is automatically taken as the origin of the plane system and an arrow appears showing the direction. You can, if desired, change the origin.

128 4. If you selected a line, select a point to define the origin, Or, If you selected a plane and want to change the origin, click the Origin field and select a point. Use the Reverse button in the dialog box or select the arrow in the geometry area to invert the direction. The contextual menus in Direction and Origin fields let you create appropriate geometry directly without having to exit the current command. 5. Click Browse... and navigate to the file containing the plane system definition. 6. Click OK when done to create a plane system along the specified direction. Creating a Semi-Regular Plane System The semi-regular option lets you easily and rapidly define a plane system comprising groups of planes with different spacings.

129 3. Select a plane or a line to define the direction of the plane system. If you select a plane, the center of the plane is automatically taken as the origin of the plane system and an arrow appears showing the direction. You can, if desired, change the origin.

130 4. If you selected a line, select a point to define the origin, Or, If you selected a plane and want to change the origin, click the Origin field and select a point. Use the Reverse button in the dialog box or select the arrow in the geometry area to invert the direction. The contextual menus in Direction and Origin fields let you create appropriate geometry directly without having to exit the current command. 5. Specify the primary subset: Specify the distance between two planes in your first group in the Spacing field. Enter the number of the last plane having the specified spacing in the End field. Click Add to confirm your first group. The first group is identified in the list view control and the Start field incremented to display the number of the first plane in your second group. Repeat to specify the spacing and the number of the last plane to be created with this spacing, then click Add. Continue until satisfied. Note: If the current spacing is the same as the spacing of the previous group, any new planes are added to the previous group.

131 Enter a prefix identifying all planes in the primary set. Planes are identified by this prefix plus a positive or negative number that increments away from the origin. Plane numbers are positive in the direction of the plane system. The origin is identified by prefix Optionally, check Allow secondary subset to group a number of planes in the primary subset together and create a secondary subset: Specify the step. For example, enter 4. Every fourth primary subset plane will belong to the secondary subset. Enter a prefix identifying all planes in this set. Notes: The plane at the origin always belongs to the primary subset. Select the subset in the specification tree to visualize all planes in this set in the geometry area. Adding Groups to Your Plane System Click in the list view control to return to the Add mode. Modifying Groups in Your Plane System Select the group you want to modify. Enter a new spacing value or modify the End value to change the number of planes in the group. Note: You cannot modify the Start value. Click Modify. The plane system is updated. Changing the number of planes in any one group does not affect the number of planes in other groups. Note: Click in the list view control to cancel unwanted modifications that have not been confirmed using Modify. Removing Groups

132 Select the group you want to remove. Click Remove. 7. Click OK when done to create a plane system along the specified direction.

133 Managing Your Project Working with a Cache System Managing Ship Project Data Managing Project Resources About the Feature Dictionary About Object Naming Rules

134 Working with a Cache System To improve system performance when working with very large documents, it is recommended that you activate the cache. This recommendation is valid when working in file-based mode as well as with ENOVIA LCA. This means that documents will be loaded in visualization mode, however, when editing structural items such as stiffeners, shapes or molded forms, the item is automatically switched to design mode. Any entities used to define the item you want to edit are also switched to design mode. Any new structures are created in design mode in the document. The cache system is managed via the Cache Management tab in the Options dialog box (Tools -> Options -> Infrastructure -> Product Structure). For more information see Customizing Cache Settings in the Customizing section of the Infrastructure User's Guide.

135 Managing Ship Project Data Proper management of project data offers the following advantages: Clear and user-friendly organization of data Easy location of items in the specification tree Facilitates management of Hide / Show capabilities for CATParts and CATProducts. This task recommends a way to manage project data that offers the above advantages. The corresponding specification tree looks like this: 1. Enter the Structure Preliminary Layout workbench (Start -> Equipment & Systems - > Structure Preliminary Layout). 2. Add the Structure Preliminary Layout level to the specification tree: Right-click the root product and select Components -> New Component from the contextual menu In the Part Number dialog box that appears, enter Structure Preliminary Layout, then click OK.

136 3. Create a wrapping surface under Structure Preliminary Layout using the Wrapping Surface command. Note: Double-click Structure Preliminary Layout to activate this level. 4. Right-click and select Components -> Existing Component... to insert CATParts containing pre-defined reference planes, typically Deck_Reference_Planes, Long_Reference_Planes and Cross_Reference_Planes. Note: It is recommended that one CATPart contain the set of reference planes in one ship direction only. 5. Right-click and select Components -> New Component from the contextual menu to create other levels as follows: Decks Transversal_Blk Longitudinal_Blk Unspecified_Blk Preliminary_Openings Basis_Bounded_Zones Composite_Bounded_Zones 6. You are now ready to start you preliminary design. You can also add the Structure Functional Design level to the specification tree and apply the same approach when managing functional design data.

137 Managing Project Resources Project resources are managed by system administrators. Typically this involves entering information such as folder paths for resources, like user dictionaries such as the feature dictionary, without which the application cannot function. What administrators enter will be visible in the Browse tab of the Project Resource Management dialog box (Tools -> Project Management ->Select/Browse...), but it cannot be changed there. Managing project resources is typically performed by an administrator. A sample project resource management file is provided with this application and by default, the application will start with this file. The following Structure Preliminary Layout-related resources are managed in this file. Project Resources Feature dictionary managing object classes Discrete values for attributes ID schema managing object naming rules ID sequence number directory: contains the last sequence number that was generated for an object. Parts catalog. Structure Discipline Resources Orientation naming conventions: contains naming conventions for ship directions. Default conventions are USA conventions listed in sample CATStrOrientNamingUSAConv. A sample file for European conventions is also supplied: CATStrOrientNamingEURConv. The default location for these resources is downloaddirectory/os/resources/msgcatalog Structure Preliminary Layout Application Resources Project name specifying the current project name. DS Default, by default. Project bounding box: defines overall project dimensions. Default dimensions (mm) are: X+ X- Y+ Y- Z+ Z The center of the box is positioned at the center of the document. Note that when the user creates the wrapping surface, the bounding box is automatically re-dimensioned to include the hull form. Openings catalog: The default location of this resource is../os/startup/components/structurepreliminarylayout/catalogs/openings/splbigscale/spl_openings_bigscale.catalog where OS is the operating system, for example intel_a (Windows). If needed, all catalogs of sketched shapes are now supported. If there is more than one project at your site, then a project resource management file is made for each project. You can select another project using the PRM command (Tools -> Project Management -> Select/Browse...). For more information on resources and how the resource management file is organized, see Understanding Project Resource Management. To check required and optional resources in the PRM file for errors, see Checking a PRM File for Errors.

138 Using the PRM Command This task shows how you can select a project for your session. 1. From the appropriate CATIA workbench, launch the project resource management (PRM) command by selecting Tools - Project Management - Select/Browse from the menu bar. The Project Resource Management dialog box is displayed: Note that when the dialog box opens the last project that you used is selected. The Select tab lists all the XML projects setup found in the directory defined by the environment variable CATDisciplinePath. This list begins with a CNEXT project which contains only the applications with their resources as defined and delivered with CNEXT. 2. Select the project of your choice, here Project. The corresponding PRM file is read and the disciplines it contains are listed. 3. Select the corresponding discipline, here Piping. Click OK to use the project and discipline you have selected. 4. The following step is used for informational purposes only - to see a list of resources for a particular discipline. To select a project you only need to take the steps explained above. Select the Browse tab. Once a project and a discipline have been selected, the dialog box lists all the applications defined for the chosen discipline, the description of the selected application, and the list of resources of that application. The list of resources displayed is always that for all applications shown in the Applications column. You should also note that the applications displayed include the applications under that particular discipline, and any applications that are at the project level, which means above the discipline in the PRM hierarchy. In the example below, the Piping discipline displays Piping Design and PID, which are part of that discipline. It also displays the Equipment, Hanger Design and Penetration Management applications, because some of their resources have been placed at the project level. The reason for placing them at the project level is that most disciplines make use of these applications.

139 When the Project Resource Management dialog box first displays, as explained in Step 1, it may contain a third tab - XML Parsing Error. This indicates that there is an XML syntax error in the file that corresponds to the Project you have chosen. Click the XML Parsing Error tab to display the error, as shown in the image below.

140 You will need to correct the PRM file to get rid of the error. Errors in defining resources in the PRM file are explained in Checking a PRM File for Errors.

141 Checking a PRM File for Errors This task shows how you can check a project resource management (PRM) file for certain errors. This tool will only check required and optional resources in the PRM file for errors. Required resources are those that the application needs, such as catalogs. Optional resources are those without which the application can still be used, and example is the ID sequencing number. There are other resources in the PRM file that are not checked at all - these are resources that add functionality to the application. Examples of these are flags that are set through the PRM file - these cannot be checked for errors because there is no way of telling what the user has set them to. See Using the PRM Command for information about syntax errors in the PRM file. The environment variable CATDisciplinePath should be defined to point to the directory where your PRM files are stored. 1. Click Tools - Project Management - Validation in the menubar to bring up the Project Management Validation dialog box. The image below shows part of it without any selections having been made. The active project, discipline and application will be selected by default when the dialog box opens. 2. Select a Project, Discipline and Application as necessary. If you select ALL in the Discipline and Application fields then the entire project resource management file will be checked (required and optional resources only). 3. Click Apply after you have made your selection. The dialog box will display the resources that have errors. The errors are explained below. If there are no errors then a message will state that all required - or optional - resources are okay, in the Status column. Select a resource to see more information about the error in the Selected Resource field below. Click on the column headings to sort by that heading. A Y in the Required column shows if a resource is required. No entry means it is an optional resource.

142 4. The errors are explained below. Also see the PRM task for more information. Resource definition has incorrect type: The value of the 'Type' field in the resource's PRM entry is incorrect. The Type field refers to file type. See the PRM task for more information. Resource not found in the project management xml file: There is no entry for the resource in the PRM file. Resource Data not found: The file or directory corresponding to the resource cannot be found at the location defined in the PRM file. Access specified for location for resource is not correct: Some entries have a field called 'Access'. This refers to the permissions set for the file corresponding to the resource. One common error is that some files need to have access set to RW (read-write) and not R (read only). 5. You can save the report. Click the Export button and enter a file name and location in the Save dialog box that displays. The file must be saved in.htm format.

143 Understanding Project Resource Management This task shows you how to manage project resources like catalogs and dictionaries. These changes can only be made at system administrator level. The project resource management (PRM) file identifies resources (such as line list catalogs, user dictionaries, etc.) to the application. Specifically, the PRM file identifies each resource and its location (directory path). The PRM file also organizes the resources by discipline and application, associating resources to specific applications. Therefore, you get the correct resource, equipment catalog for instance, for the resource you are working in. It's hierarchical structure allows you to share resources, so that you do not have to place duplicate copies of the same resource in several directories. The PRM file is also used for certain other purposes, such as setting flags. These are explained below. A sample file is provided with this application, and it is best to make a copy of it and edit it. The default location is...intel_a\startup\equipmentand Systems\ProjectData and the file is named Project.xml. The application will function even if the user does not enter information particular to his site, but nothing can be saved. Therefore, the first task an administrator needs to do is enter information relevant to his site or project. 1.If there is more than one project at your site you will need to make a project resource management file for each project. You can name the file anything you want to and change its location too (see below). However, you must set the variable in the Environment Editor. You do this by opening the Environment Editor dialog box and entering against the line CATDisciplinePath the directory in which your project resource management files are: If you have more than one project resource management file then by default the application will start with the file named Project.xml, if there is such a file, or the last file used. If you wish to select another resource management file you must open it by clicking Tools - Project Management. Go to the Select tab and select the file and discipline you need. This dialog box shows each resource available to you, unless the value of "Visible" (see below) against a resource or application is set to No. 2.The resource management file is organized into several sections to make it easier to manage and utilize resources. The image below shows its hierarchical structure, with an exception, which is explained below. "Other disciplines" refers to other disciplines like Tubing, or AEC V4 to V5 Migration Discipline, that are placed at the same level. They are not shown in this image for reasons of space.

144 The Project box refers to the project for which the PRM file has been created, and will frequently be identified by the file name. In this case it is Project.xml. When you look at the Project.xml file you will see that the resource listings begin with project resources. Any resources you place under the heading Project Resources can be used by all applications that are included in the file. In the sample file you will see items like zones, feature dictionary and application-generated object names in this section. All disciplines and applications shown under project resources will be able to access the resources identified under the heading project resources. The next level is the discipline level. All resources placed under a discipline, such as Piping, can be used by all the applications which are listed under it. In the example above, Piping Diagrams, Piping Design and Equipment applications are shown under the Piping Discipline. Resources such as various catalogs and report definitions are listed at the discipline level and can be accessed by all applications that belong to that discipline. The next level of resource management is the application itself. Any resource referred to at this level can only be used by that application. Resources like catalogs, files that contain connector attributes and resolved parts directories are listed at this level. Equipment Arrangement and Hanger Design have been placed under several disciplines. These applications are considered multi-discipline because their resources are used by all disciplines. When you are working in these disciplines you may need Equipment or Hanger resources. However, in different disciplines you may not use the same resources from Equipment Arrangement or Hanger Design and this structuring allows you to place different different resources under each discipline. For instance, under the Piping Discipline, Equipment Arrangement may have a different catalog (with Piping related equipment only) than under the HVAC Discipline. Equipment and Hanger applications have also been placed at the project resource level, primarily to allow sharing of resources, under the headings "Equipment Application Resources" and "Hanger Design Application Resources."

145 To explain: If you are working in Piping Design you are in the Piping Discipline. You select the discipline by clicking Tools - Project Management, or simply by opening an application, which will activate the correct discipline. For this to happen your PRM file must be set up correctly. Now, while in the piping workbench, you want to place equipment in your document, and you launch Equipment Arrangement. When you do so you will only have access to equipment resources that are identified in the PRM file under the piping discipline, for instance the "piping equipment catalog," containing piping related equipment. But let us assume that in your project you have certain types of equipment that are used by all disciplines. You can create a catalog that contains all this common equipment and identify it under "Equipment Application Resources" at the project level (it should not be identified under discipline also). When you do this you will have access to this catalog when you open Equipment Arrangement under any discipline. Some applications have the entry "Visible = yes". If you set the value to No then this application cannot be used and will not be visible in the Tools - Project Management dialog box. 3. A resource entry looks like this: <Resource Name="PipingIDSchema" Description="Piping ID Schema Directory"> <ID Type="Path" Driver="File" Location="..\..\EquipmentAndSystems\Piping\DataDictionary"/> </Resource> You should not change the Resource Name, even if you replace a resource with a different one. You can change the Description if you want to - this is a brief explanation of the resource. The Type field refers to file type. If the Type field says Catia, it refers to a file type unique to Catia, such as.catalog. The type Misc is used for resources which are of a type not unique to Catia and must be opened in another way. The type Path is similar, except that in the Location field only the directory in which the resource is located is named. If your resources do not reside in Enovia, enter File in the Driver field. Define the Location field as follows: As shown in the resource example above, the location entry is relative - it is relative to the entry you made in the Environment Editor as shown in Step 1. The entry in the location field will be added to the entry you had in the Environment Editor and it is in that location that the application will look for the resource. Which is why it is preferable to enter absolute paths - including the drive letter - in the location field. If your resources are Enovia-based, enter EnoviaV5 in the Driver field. For Enovia-based resources, all you need to enter in the Location field is the file name of the resource without the file extension. For instance, the catalog PipingParts.catalog would be entered as PipingParts. The Location field is sometimes used to enter a value for a flag or behavior, such as 0 or 1, or True and False. Some resources have the entry "Visible = yes". If you set the value to No then this resource cannot be used and will not be visible in the Tools - Project Management dialog box. Some resources have the entry Access="RW" or "R". These refers to file permissions: read-write or read. When you change from using file-based resources to Enovia-based resources: You must go through the PRM file and change the "Driver" and "Location" entries as noted above. This must be done for all resources that have been placed in the Enovia database.

146 4.The Project Resources listed in the sample Project.xml file are described in following sections, beginning with the resources referred to under Project Resources: ID schema resources: The "location" lists the directory where the rules for naming objects are stored. Use the default location provided in the sample file. You need to have this for every application you use. In addition, there is an entry for "MultiDisciplineIDSchema." This location is used for objects -such as zones - that are used by all disciplines. User dictionary resources: In the location field enter the name of the CATfct file for each application. You do not need to enter the location. The CATfct file is used to store all the classes and attributes created by you. The default names for CATfct files in each application are included in the sample project.xml file and you should use these names unless you have created a different CATfct file, or changed the default name. There is also a MultiDisciplineUserDictionary - this CATfct file can be referred to by all applications. Zones catalog: The zones that you create need to be stored in a catalog accessible to all users, because they are shared. The default location is CATMldZone.catalog. Even though zones are only created in schematic applications, other applications may use them when documents are moved from schematic to 3D. Enter a different name or location if you change them. Discrete values: Many attributes have discrete values and this directory is used to store them. Schematic driven flag: This is a flag that needs to be set for schematic driven routing and parts placement. If the value of "Location" is set to 0 then individual users can check or uncheck an option that allows schematic driven 3D design. If the value is set to 1 then the option "schematic driven" is always selected and users cannot uncheck it. Delete Part On Run: This entry is used to control whether all parts on a run will be deleted when you delete the run. If you enter the value of "Location" as 1 then the parts will be deleted. If you enter the value 0 then the parts will not be deleted when you delete the run. Graphic representations: When you create graphic representations for a part you need a file in which to store the categories (single, double, etc.). That file is created within an application, as you will see later. There is also a file under Project Resources because the categories must be available to all applications. If you add a new category you must include it in this file too. Enter a new location and file name if you want to change them. Penetration openings catalog: The profiles of the holes you may want to make through walls and partitions to pass pipes and ducts are noted in this catalog. If you make a new profile you must enter it here too. Enter a new location and file name if you want to change them. ID Sequence Number directory: The IDSequenceNumbers directory contains the last sequence number that was generated for an object. You should specify a location for it. Importer CATfcts: This lists the location of your CATfct files, and is used when migrating V4 models to V5. If you change the location of the CATfct files you must enter the new location in the "Location" field. You do not need to do anything if you continue to use the default location. Reference Grid System: Location of the CATPart that contains the reference grid definition used by applications. You need to modify this entry if you change the location of the CATPart or rename it. Discipline super class: This is a text file that lists the object classes that will be visible in a class browser when you are in the Equipment Arrangement workbench. You can have files at project, discipline and application level. The filter will only work with a user-generated PRM file. Computed attributes: This entry shows the location of the ComputedAttributes.txt file. The computed attributes contained in this file will display in the Properties dialog box. You can change the location of this file, and update the PRM file accordingly. You can also change the entries in the file. Unique reference part number options & partially resolved reference part number options: These two entries define how a placed part will be named. 'Unique reference' parts are those that have at least one property (or all properties) that can have infinite values. An HVAC duct is an example. 'Partially resolved' parts are those in which the values of all properties are defined by a design table. Valves are an example. In this entry, if you enter 1 in the Location field then the name of the placed part will be derived from the design table. If you enter 2 then the name will be derived from the object naming rules.

147 5.The next level, as explained above, is the Discipline level. Resources placed under the Discipline category can be used by all the applications in that discipline. The sample Project.xml file places the following resources at the Discipline level. Each entry names the file and gives its default location. If you intend to use different resources, which is likely, then you must enter the new file name and location, as appropriate. The following resources are referenced, but not all disciplines will have all of these resources. Specifications catalog Insulation specifications catalog Material specifications catalog Standards catalog Design rules: You need to use the default location and file name Parts catalog name and location: contains parametric parts Piping lines shared catalog: The file where shared piping lines are stored and its location. Sample data directory: This is the location where the reports you run will be stored. Report definitions directory: The formats (definitions) you create for running reports are stored in this directory. 6.In addition to resources placed at the Project and Discipline levels, resources are also placed at the application level and are only available to the application under which they are placed. 2-D applications have all or most of the following resources. Component catalog: The parts catalog. Shared instrument lines catalog. Annotation catalog. Sample data directory: When you create graphic representations for a part you need a file in which to store the categories (open, closed, etc.). If you add a new category you must include it in this file too. Enter a new location and file name if you want to change them. Design rules for Equipment Arrangement: This is used when assigning a part type to a 2D part. The parts catalog for Equipment Arrangement: This is used when assigning a part type to a 2D part. 3-D applications will have most of the following resources or entries. Graphic representations file: When you create graphic representations for a part you need a file in which to store the categories (single, double, etc.). If you add a new category you must include it in this file too. Enter a new location and file name if you want to change them. Connector attributes file: This file lists the attributes that will be inherited (from the part) by a connector when you are placing it on a part. If you want to make changes to the attributes you want a connector to inherit you must do it in this file. Do not change the name or location of this file. Resolved parts: When you place a parametric part in a document it assumes specific dimensions. Once a part has specific dimensions it is placed in the Resolved Parts catalog. The location of the default Resolved Parts catalog is listed here. Design rules: You need to use the default location and file name. Parts catalog name and location: contains parametric parts Sample data directory: This is the location where the reports you run will be stored. Report definitions directory: The formats (definitions) you create for running reports are stored in this directory. Graphic Replacement True View Catalog: This is the catalog in which the 2-D equivalents of 3-D endstyles are stored. See Drawing Production for more information. Growth Factor: Some applications allow you to reserve space in some parts for future growth. You can, for instance, reserve space in a conduit for future growth. The space saved for future growth will be equal to

148 the value you enter in the "Location" field. If you enter 0.2 it means that 20 percent of the space in a conduit will be reserved for future growth and you will only be allowed to use 80 percent of the space in it. 7.The AEC Migration Discipline refers to a product that enables you to migrate V4 models to V5. It has Piping Design, Piping and Instrumentation Diagrams, Equipment Arrangement, Tubing Design and HVAC Design resources under it. Most resources have been described above and do not need further explanation. Enter the location and file names if they are different from those in the sample Project.xml file. In addition, under the heading AEC V4 V5 Migration there are several options you should know about. They are explained below. AEC V4 V5 Migration There are several options that you need to set to True or False. The first several are about migrating data to Piping and Instrumentation Diagrams, Piping Design, Equipment Arrangement, Tubing Design and HVAC Design and Structures. If a V4 model has data of all these types, but you have set two of them to False, then you will only receive V5 data relating to the applications set to True. If you want data of all types to be migrated then you must set all the options to True. Other options are: Create runs without parts: If set to True a run will be migrated without the parts. ImportPipingLine (or other type of line): If set to True a line will be created in the V5 Piping Line catalog if it does not exist. When set to False, the migration process will stop if the line does not exist in V5. Mapping Table: You need to enter the location and name of the migration mapping table if you change the default name or location. MigratedPIDNoShowSheetFormat: The sheet format (also known as title block) will not be visible if the value of "Location" is set to False. MigrateXXXWithMissingLines: If set to True the sheet will be migrated even if some Lines cannot be. If set to False the migration process will stop if missing lines are encountered. MigratedXXXSheetSize: Enter the size in the Location field: Letter, Legal, A0, ISO/A1, ISO/A2, ISO/A3, ISO/A4, ISO/A, ANSI/B, ANSI/C, ANSI/D, ANSI/E, ANSI/F, ANSI). MigrateEquipmentWithMissingGeometry: If set to True, Equipment with missing geometry will be migrated. If set to false, such equipment will not be migrated. MigrateObjectWithMissingAttributes: If set to True, objects will be migrated even if some of the attributes do not exist in V5.. If set to False, the objects will not be migrated if some of the attributes do not exist in V5. 8.In addition to some of the resources explained above, the Structure Discipline includes the following resources or entries: Sections catalog: If you change the default location of the AISC_BigScale catalog then enter the location in this entry. The location should include the directory AISC in which the catalog should reside, so that the path reads:...aisc\aisc_bigscale.catalog. Structure sections path: This is the location of the directory where resolved structure sections are located before they are extruded for placement in a document. Structure Thickness List: This is the location of the thickness list sample file, which contains the list of thicknesses that can be applied to a plate. Structure openings catalog: Location of the openings parts catalog. Structure materials catalog: Location of the structure materials catalog. Structure detail design: Location of the catalog that contains user defined features. Naming section characteristics: Location of the NLS file that lists names of sections whose names should not be changed. This is for internal use. Do not change anything in this entry. Structure Functional Connections Catalog: Location of the Structure Functional Connections Catalog. This

149 catalog contains the names of connection types between objects. Project Bounding Box: This specifies the dimensions of your project - if you are designing a ship then it will be set within these dimensions. You can define the unit used for measuring - the default is millimeter - and change the default values for each direction. The values are measured from the origin (000). 9.Make sure to save your changes.

150 About the Feature Dictionary The feature dictionary manages object classes. Object classes are classifications under which you create various objects. In the sample dictionary provided with the application, three main object classes (wrapping surface, molded form, and bounded zone or compartment) and a number of sub-classes are managed. Note: In the application, these object classes are managed via the class browser. The feature dictionary file has the extension CATfct. To view the sample feature dictionary: 1.Open the CATStrPreliminaryLayoutSample.CATfct file. By default, this file is located in the install_folder under /resources/graphic. The Feature Dictionary Editor opens showing the sample dictionary. The Classes View displays all the classes available in the document, i.e. the predefined classes included in the application.

151 2.Double-click Bounded Zone (corresponds to compartment) to view associated class attributes. Existing attributes or properties are displayed in the Inherited attributes and Local attributes boxes. Inherited attributes are those inherited from the super class to which this class belongs. Local attributes are properties added to the class itself. The following table lists the object classes and corresponding attributes provided in the sample dictionary. Wrapping Surface Type Molded Form BulkheadIntegrity FrameLocation InsulationTreatments PaintSchedule SurfaceTreatments Tightness Bounded Zone or Compartment FunctionNumber HVACCategory Location PaintThickness Attributes or properties assigned to object classes can be browsed via the Properties dialog box (right-click feature in specification tree and select Properties from the contextual menu). You can add sub-classes and attributes to the sample dictionary, or if you want, you can create a new feature dictionary. You may, for example, want to create several sub-classes under wrapping surface in the sample dictionary for deckhouses, internal and external wrapping surfaces. The feature dictionary (CATfct file) must be kept in the default location. If you change its name or create a new dictionary, you must make the corresponding change in the project resource management file. You can also define or modify the object naming rules of objects integrated into the feature dictionary in the Feature Dictionary Editor workbench. For more information, see Using the Feature Dictionary Editor in the Infrastructure User's Guide.

152 About Object Naming Rules Structure Preliminary Layout provides a set of default naming rules or unique identifiers for the objects you create. This identifier consists of a prefix that identifies the type of object it is, followed by a unique number. You may want to modify these rules to suit your own requirements: For objects integrated into the feature dictionary, use the Define/Modify ID Schema command in the Feature Dictionary Editor application. For all other objects, you must edit XML files directly. By default, sample XML files are located in the install_folder under startup/equipmentandsystems/structurepreliminarylayout/datadictionary. Modifying or defining object naming rules is typically performed by an administrator. For more information, see Modifying the Object Naming Rules in the Infrastructure User's Guide.

153 Structure Preliminary Layout Package in Knowledge Expert A Structure Preliminary Layout package is supported by Knowledge Expert. This package can be accessed via the object browser and objects, attributes and methods in the package used in expert relations. You can, for example, write a rule to change the color of all molded forms of a given type. The package contains the following main objects: CATSPLBooleanOperator CATSPLBoundedZone CATSPLWrappingSurf CATSPLMoldedForm. All other objects listed in the browser derive from the above main objects, for example Deck derives from CATSPLMoldedForm. These objects or sub-classes are managed in the sample feature dictionary. For information on object attributes and methods, see Structure Preliminary Layout in the Reference Information section of the Knowledge Expert User's Guide.

154 Interoperability Working with ENOVIA LCA Working with SmarTeam

155 Working with ENOVIA LCA Optimal CATIA PLM Usability Recommended Methodology Multiple Design Options, Querying for Compartments Penetration Management

156 Optimal CATIA PLM Usability When working with ENOVIA LCA, a new mode ensures that you only create data in CATIA that can be correctly saved in ENOVIA. ENOVIA LCA offers two different storage modes: Workpackage (Document kept - Publications Exposed) and Explode (Document not kept). Workpackages let you organize data efficiently in easily manageable units. They also facilitate concurrent engineering. Structure Preliminary Layout In Structure Preliminary Layout (SPL), data is saved corrected in both modes, however, Explode mode is the recommended mode since this mode lets you manage Structure Preliminary Layout objects individually in ENOVIA. All Structure Preliminary commands are thus available at all times. Structure Functional Design Structure Functional Design (SFD) has been configured to work in the Workpackage mode. The Structure Functional Design workbench is set up such that the user cannot create functional objects without first creating a panel system. When first entering the workbench, all other commands are therefore unavailable. The panel system has been defined as an ENOVIA LCA workpackage. Ship Structure Detail Design Ship Structure Detail Design (SDD) has been configured to work in the Workpackage mode. In Ship Structure Functional Design, the block scheme and paneling system have been defined as ENOVIA LCA workpackages. The safe save mode means that certain commands (Automatic Connection, Manual Connection, Connection Body and Mitering) are unavailable (i.e. grayed). You cannot make connections or miter cuts between two different workpackages. Recommendation: Open the paneling system in a new window and create connections within the same workpackage.

157 Recommended Methodology The recommended methodology for working with ENOVIA LCA is: Create a product in ENOVIA Send your ENOVIA product to CATIA Work on your design in CATIA, whether from scratch or modifying an existing design Save your CATIA data in ENOVIA. To ensure seamless integration: You must have both a CATIA V5 and ENOVIA LCA session running. In the Product Structure workbench of CATIA V5, click the Connect to Enovia LCA icon to establish the connection between CATIA V5 and ENOVIA LCA. Creating a Product in ENOVIA At the top level of the ENOVIA product hierarchy is the product class root. This is the highest entity in a product structure and is used to group products. Products can be created directly under this level or under an intermediate level called the product class depending on how you want to structure your data. It is not necessary to create product classes, but the product class root and product must always exist. This is the product that will be sent to CATIA and is mapped to the CATIA document root. 1. In the ENOVIA home page, open the Engineering Life Cycle folder and double-click the Product Classes folder. 2. In the Product Class browser, click the New Product Class Root icon in the topmost toolbar. 3. Enter a meaningful name for your product class root in the Product Class ID field and then click Add. 4. Right-click the product class root you have just created and select New -> Product from the contextual menu. 5. Enter a meaningful name for your product in the Product ID field and then click Add. 6. Don't forget to click the Save icon in the topmost toolbar to save the structure in ENOVIA.

158 Sending an ENOVIA Product to CATIA 1. Right-click the ENOVIA product and select Send to -> CATIA V5 from the contextual menu. This is what you see in CATIA: the ENOVIA product is mapped to the CATIA document root. Note: You also need to send any existing workpackages you need from ENOVIA. If you send a workpackage, the product is also sent - you do not need to send both. Saving CATIA Data in ENOVIA 1. In the Product Structure workbench of CATIA V5, click the Save Data in ENOVIA LCA Server... icon in the

159 ENOVIA LCA toolbar. The Save in ENOVIA V5 dialog box appears showing objects to be saved and set to the correct save mode and save options. The dialog box below shows Structure Functional Design objects. 2. Click OK in the dialog box. A Save in ENOVIA V5 progress bar lets you monitor the progress of the operation. In ENOVIA LCA: The Structure Functional Design panel system, and Ship Structure Detail Design block scheme and paneling system are each saved as one document. All Structure Preliminary Layout items created under the CATIA root and any new components are saved in Explode mode; new products are saved in Workpackage mode. No doubt you will need to refresh the ENOVIA product structure to view the data you have just saved. If the CATIA Document Root is Not an ENOVIA Product Save your work temporarily. Create a product class root and product in ENOVIA. Send the ENOVIA product to CATIA. Insert the components (Insert -> Existing Component) containing the work you saved temporarily above. Save your work in ENOVIA.

160 For more information, see the CATIA / ENOVIA Interoperability User's Guide and the appropriate ENOVIA LCA guide.

161 Multiple Design Options, Querying for Compartments To assist you in your structure preliminary layout, ENOVIA LCA provides capabilities letting you manage multiple design options and run compartment queries for application objects stored in the ENOVIA LCA database. Multiple Design Options Managing multiple design options corresponds to the ENOVIA LCA capability of managing part versions. The recommended methodology to do so is: Work on your new design option in CATIA. Create a new part version in ENOVIA: You should create as many part versions as different design options. Attach the CATIA document to the part version. For more information, see Manage Part Versions in the ENOVIA LifeCycle Applications Engineering LifeCycle guide. Querying for Compartments The ENOVIA LCA Search Tree enables you to query the ENOVIA LCA database for compartments by type. For more information, see Manage Searches in the ENOVIA LifeCycle Applications Engineering LifeCycle guide.

162 Penetration Management This section discusses penetration management, which refers to the process of routing a pipe or a duct - as an example - through a structure. If you are working with a ship, for instance, you may need to create penetrations through bulkheads, move objects, or reroute your pipe or duct, in order to do so. Note: The penetration management function works with the ENOVIA environment only - and you must be in the ENOVIA product structure. You must take certain setup steps before using this function. See Penetration Management Setup to learn how to set up the function. Querying for Penetrations Create a Cutout Sketch Adding an Object to a Penetration Penetration Management Setup

163 Querying for Penetrations This task shows you how to query your document to identify penetrations and cutout solutions. Within the overall design process, querying is done after a penetration request has been created, to determine what these requests are. The subsequent step will be to create cutout sketches. There are two methods for querying penetrations. You can query locally by selecting the object (bulkhead, plate, etc.); or select the product in the specifications tree, which will generate a list of all penetrations in the product and all sub-tier products in your document. 1. With your document open, click on the Penetration Management button. The Penetration Management dialog box opens. Select the object which is being penetrated. 2. The object you selected will appear in the Selected object to query field. The Penetration Management dialog box lists the penetrations associated with the object you have selected and the current status. To retrieve geometry that has not been loaded from ENOVIA, select the penetrations you want to query, then click the Load Geometry button. The list of penetrations will be updated.

164 3. To create a cutout sketch you will select one or more penetrations from the list. This process is explained in Creating a Cutout Sketch.

165 Creating a Cutout Sketch This task shows how to create a cutout sketch for a penetration. The sketch may be created using penetration design rules, by selecting from a list of cutout shapes, or by creating the cutout manually. When creating a cutout using design rules, the cutout shape and clearance are defined by penetration cutout rules and the penetration shapes catalog. 1. Select the penetration from the Penetration Management dialog box. The related objects highlight in your document, and will be used in calculating the penetration location. 2. Click the Create Cutout Sketch button and the Create Cutout Sketch box will display. Select the Rules tab is you want to use the design rules to create a cutout sketch.

166 The Create Cutout Sketch dialog box displays the shape and size for the proposed sketch, as computed by the design rules. Click OK if you accept it. 3. If, instead, you want to select a sketch from a catalog, then select the Standard Catalog tab and the Catalog Browser button. The Catalog Browser displays. Select a sketch to place it.

167 4. If you want to create a sketch then select the Manual Sketch tab. The Sketcher will open. Create your sketch and click the Exit Workbench button. The sketch will be placed. 5. The Place on Side buttons allow you to place the cutout sketch on one side or the other of a structure, and is used for visibility purposes. 6. Click OK. You must save the document before you can take the next step.

168 Adding an Object to a Penetration This task shows you how to add an object to a penetration. By adding an object to a penetration you are associating the cutout sketch you created earlier to the penetration record. Before you take this step you must save the document in ENOVIA. 1. With your document open click the Penetration Management button and query the penetrations. The Penetration Management dialog box will open listing the active penetrations. Select the penetration for which you want to add an object. 2. Click the Add Object to Penetration button. The Add Objects to Penetration dialog box opens displaying the Penetration ID you selected. 3. Select the cutout sketch(es) in your document, or from the specifications tree, that you want to add to the penetration and click OK. The objects are added. 4. Click OK to close the Penetration Management dialog box.

169 Penetration Management Setup This task explains the setup process for defining a penetration cutout sketch, and identifies some of the processes involved. Penetration management uses design rules that are Knowledgeware-based. To modify the sample rules provided with this application, or to create new design rules, you must know how to use Knowledgeware. Read the documentation for that product to get more information. In addition, you must incorporate certain data particular to this application when creating new rules. That is explained below. You may also need to refer to ENOVIA-LCA documentation for ENOVIA-specific tasks. If the Penetration Management Tools toolbar is not displayed then click View - Toolbars and select it. Penetration management refers to the process of routing a pipe or a duct - as an example - through a structure. If you are working with a ship, for instance, you may need to create penetrations through bulkheads, move objects, or reroute your pipe or duct, in order to do so. The penetration management function works within the ENOVIA environment only - you must be in the ENOVIA Product Structure. 1. Modify the project resource management (PRM) file to reflect the location/names of your resource files. The penetration function uses three PRM resources. The names are: PenetrationCutoutRules, PenetrationOpeningsCatalog, and PenetrationShapesCatalog. Sample rules and catalog are provided with this application. The location is...intel_a\startup\components\penetrationcatalog. See Understanding Project Resource Management for more information about the PRM file. 2. The outlines of openings are dependent on the shapes defined in the Penetration Shapes catalog. You cannot define an outline in the design rules that does not have a corresponding shape in the catalog. Shapes defined in the sample catalog are: oblong, round, rectangular, square and rectangular radius corner. You can change the values of the parameters of the shapes in the catalog, and you can add new shapes to it. You can remove, replace or rename the sample shapes. Each shape is a parametric part created with the Part Design product, and is stored in the same directory as the catalog. The oblong shape document, for instance, is OblongShape.CATPart. See Part Design documentation for information about using that product. To add a shape you must create it with Part Design and store it in the catalog using standard catalog building procedures. See Creating a Catalog and associated tasks in the Catalog section to learn more about creating and modifying catalogs. These are standard parametric parts and there are no special requirements for building them. When building new shapes you should note that the description name you use in the catalog is the name that will display when you are creating a cutout sketch.

170 3. Most penetration cutout designing will be done using the design rules, although you have the capability of manually defining cutouts, as explained later in this section. The rules work with the shapes in the catalog to determine the final size of the opening. You can add various parameters to the rules using Knowledgeware. However, the function of the sample rules supplied with this application is mainly to determine the shape of the outline, based on the shapes available in the catalog; and calculate the size of the opening. The cutout size is calculated from the sizes of the objects involved in the penetration, with the addition of required clearances. 4. Design rules can be modified, and new ones created, using Knowledgeware. However, there are certain points you must incorporate in a design rule for it to work correctly with this function. The following information is meant for an administrator, or whoever is creating the design rule. You can see examples in the sample rule, which is reproduced below. A penetration cutout rule should: Create a variable (defcutout) to hold the DefinePenetrationCutoutShape object, which will communicate the cutout definition to the penetration management command. Calculate the size of the cutout, using attributes of the penetrating and penetrated objects. The NewDefinePenetrationCutoutShape function creates the temporary object that holds the cutout definition. The penetrating object (p1) and penetrated object (p2) are specified. The ShapeName attribute selects the parametric part that defines the shape. The SkewTolerance attribute sets the allowed SkewTolerance for the penetration. The SetAttributeDimension function (or another SetAttributeXXX function) specifies a parameter name in the parametric part, and its value. This function is used repeatedly to set each parameter of the parametric part. A sample rule is reproduced below:

171 Structure Preliminary Layout: Working with SmarTeam Structure Preliminary Layout documents can be stored in SmarTeam. Documents are managed in projects in SmarTeam. You must therefore create a SmarTeam project. To ensure seamless integration, you must have both a CATIA and SmarTeam session running. 1. In CATIA, specify your document environment: Select Tools -> Options -> General -> Documents tab Set SmarTeam to Allowed. 2. Still in CATIA, select Connect from the SmarTeam menu to establish your CATIA - SmarTeam connection. 3. To save a CATIA document in SmarTeam: Select Save from the SmarTeam menu. The Projects Manager dialog box displays. Search for the SmarTeam project you want to save your document under. Select the project Select the Link to Projects checkbox, then click Save. Your document is saved in SmarTeam.

172 4. To open a SmarTeam document and send it to CATIA: Select Find Document from the SmarTeam menu in CATIA. The Search Editor dialog box displays. Select CATIA Products, then click Run. The CATIA Products dialog box displays. Right-click the project and select File Operation -> Open in the contextual menu. The document associated with the SmarTeam project opens in CATIA. For more information on SmarTeam capabilities, see the appropriate guide.

This type of customization is stored in permanent setting files: these settings will not be lost if you end your session. 1. Select the Tools -> Options command. The Options dialog box appears. 2. Select the Equipment & Systems category in the left-hand box. 3. Click the Structure Preliminary Layout sub-category. The Design, Drafting and Offset Data tabs appear. The Design tab lets you set default colors for main items. The Drafting tab lets you customize lines drawings. The Offset Data tab lets you manage the output formats for your offset data. Two other settings, Keep link with selected object and Create external references as shown elements, are also needed to ensure associativity between the items you create and entities selected to create them, and to ensure better management of the import mechanism, respectively. 4. Select Infrastructure -> Part Infrastructure -> General, then select Keep link with selected object and Create external references as shown elements. 5. Set options in Structure Preliminary Layout tabs according to your needs. 6. Click OK in the Options dialog box when done.

178 Design Settings The Design tab contains two categories of options: Default colors and Import option. Default Colors Use the color chooser to define the default color for molded forms, bounded zones (compartments) and boundaries. By default, colors are as shown above. Import Option Selecting this option stores external references (surfaces and planes) used to create molded forms and compartments in associated CATParts. Click to clear this option to improve performance by significantly reducing data size. If cleared, external references are not stored in the CATPart. When editing, necessary geometry is loaded in transparent fashion. By default, this option is selected.

179 Drafting The Drafting tab contains five categories of options letting you customize your lines drawings: Geometry to display Waterlines view Waterline position Body plan Midship position Geometry to Display Select the option defining how the shape of the ship is shown on lines drawings: Wireframe only or Surface only, or Both. By default, the option is Wireframe only. For a body plan, ensure Wireframe only is selected. Waterlines View Select the option defining the view looking at the ship from above: Symmetrical or Asymmetrical depending on whether or not the ship is symmetrical about the centerline. This generates a halfbreadth or full-breadth view respectively. Typical half-breadth view:

180 By default, the option is Asymmetrical. Waterline Position Select WaterLine reference plane If this option is selected, the waterline is located at the selected reference plane in the 3D document. Specify value (absolute z coordinates If this option is selected, the waterline is located along the Z direction at the absolute coordinate entered in the Absolute Z coordinate box. By default, the option is Specify value.

181 Body Plan Select the option defining the view showing the shapes of the frame lines: Symmetrical or Asymmetrical depending on whether or not the ship is symmetrical about the centerline. The generated view is made of two parts. If the ship is symmetrical, only one side of the ship is shown (usually the portside) and the right-hand part looks aft at the forward portside of the ship, while the left-hand part looks forward at the after half of the portside. If the ship is asymmetrical, both sides of the ship are shown. Typical body plan: To generate this drawing, you need to define the midship position (see below). By default, the option is Asymmetrical.

182 Midship Position Select middle station If this option is selected, the midship is located at the selected reference plane in the 3D document. Specify value (absolute x coordinates) If this option is selected, the midship is located along the X direction at the absolute coordinate entered in the Absolute X coordinate box. By default, the option is Specify value. For the options in this tab page to be taken into account, you need to select Project 3D wireframe, Project 3D points and Apply 3D specifications located in Mechanical Design - > Drafting -> View -> Geometry generation/dress-up frame. By default, Project 3D wireframe and Project 3D points check boxes are cleared, and the Apply 3D specifications check box is selected.

183 Offset Data The Offset Data tab contains one category of options to manage output formats, for example HTML pages or CSV files, for your offset data: Global. Global New / Edit / Delete Use New, Edit or Delete to add new stylesheets, and edit or delete existing ones. Sample stylesheets (OffsetDataAsHTML.xls and OffsetDataAsCSV.xls) for two formats, HTML and CSV respectively, are provided. By default, they are located in the installation folder under OS/startup/EquipmentAndSystems/StructurePreliminaryLayout/StyleSheet. Apply XSL Transformation Select this check box to take all stylesheets into account and choose the format of your output data when interactively generating your offset data. By default, this check box is cleared and only XML files will be generated.

184 Customizing Standard Views You can tailor standard CATIA views to suit shipbuilding conventions and standards.
