3 Page 3 Preface 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. 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).

26 Page 26 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.

27 Page 27 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). Associativity To ensure associativity between the items you create and entities selected to create them, you must check the Keep link with selected object option.

Browsing Project Data Wrapping Surfaces Molded Forms Compartments Boundaries Openings Exporting Data in IDF Format Generating Offset Data Creating Reports Producing Lines Drawings Creating Plane Systems Managing Your Project Structure Preliminary Layout Package in Knowledge Expert

28 Browsing Project Data Page 28 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.

29 Page 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.

30 Page 30 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.

31 Page 31 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.

32 Page 32 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.

33 Page 33 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.

34 Page 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.

35 Page 35 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.

36 Page 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.

37 Page 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.

38 Page 38 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.

39 Page 39 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.

40 Page 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.

41 Creating Deckhouses Page 41 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.

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:

43 Page 43 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.

44 Page 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.

45 Page 45 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.

46 Page 46 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.

47 Page 47 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.

48 Page 48 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.

49 Page 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.

50 Page 50 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.

51 Page 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.

52 Page 52 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.

55 Page 55 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

56 Page 56 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.

57 Creating Simple Molded Forms Page 57 This task shows you how to create simple molded forms. Have created your wrapping surfaces. 1. Click the Molded Form icon. The Molded Form Definition dialog box appears. 2. Click Change... opposite Object class to change the molded form class.

The two underlying sketches giving the basic shape of your molded form. Reference planes must be created in a new part. Do not use existing part axis system planes. You can edit the underlying sketches to modify your molded form. 6. If desired, specify an offset distance to offset the molded form from the reference plane. A positive value offsets the molded form in the X+ direction. 7. Define the limits in the geometry area and watch your molded form being trimmed to the limits you select. Limits can be the hull form, other molded forms or GSD planes. If you select the hull form: The Basic Wrapping Surface Selection dialog box appears listing basic wrapping surfaces with those set as default surfaces in the Wrapping Surface command in the Selected box. You can move surfaces from Not Selected to Selected boxes and vice-versa using arrows. Double arrows move all surfaces from one side to the other. To select a complete wrapping surface, select all component basic wrapping surfaces.

59 Page 59 Click OK in the dialog box when done to select all basic wrapping surfaces listed in the Selected box. Define your list of default surfaces in the Selected box and check Keep as default and surfaces will be set as default surfaces in the Wrapping Surface command. Selected limits are listed as limiting elements in the Molded Form Definition dialog box. 8. If necessary, click Other side in the dialog box to extend the molded form in the direction opposite that shown in the preview.

122 Page 122 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 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.

123 Page 123 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.

124 Page 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.

125 Understanding Project Resource Management Page 125 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), but it cannot be changed there. 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, where OS is the operating system, for example intel_a (Windows NT). 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. If there is more than one project at your site, then a project resource management file is made for each project. You can open another resource management file using the Project Management command (Tools -> Project Management). For more information on how to do so, see Using the PRM command in the Infrastructure User's Guide. For more information on resources and how the resource management file is organized, see Understanding Project Resource Management. Managing project resources is typically performed by an administrator.

126 About the Feature Dictionary Page 126 The feature dictionary manages object classes. 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. To view the sample 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.

127 Page 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. You can also define or modify object naming rules using the Define ID Schema icon in the Feature Dictionary Editor workbench. For more information, see Using the Feature Dictionary Editor in the Infrastructure User's Guide.

128 Page 128 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.

129 Page 129 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.

131 Page 131 Working with ENOVIA LCA: Optimal CATIA PLM Usability When working with ENOVIA LCA, Optimal CATIA PLM Usability ensures that you only create and edit 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). In Structure Preliminary Layout, data is saved correctly in ENOVIA LCA 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. Recommended Methodology The recommended methodology for working with ENOVIA LCA is: Create a product class root (PRC) and product in ENOVIA LCA. Send your ENOVIA document 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 and ENOVIA session running. 1. In the Product Structure workbench of CATIA V5, click the Init Enovia V5 Connection... icon to establish the connection between CATIA V5 and ENOVIA LCA. 2. In ENOVIA LCA, send your ENOVIA document to CATIA. 3. Work on your design in your CATIA V5 application. 4. In the Product Structure workbench of CATIA V5, click the Save Data in ENOVIA V5 Server... icon to save your CATIA data in ENOVIA. The Save in ENOVIA V5 dialog box appears showing objects to be saved and set to the correct save mode and save options. All structural items created under the root and any new components are saved in

132 Page 132 Explode mode; new products are saved in Workpackage mode. 5. Simply click OK in the dialog box. If the CATIA document root is not an ENOVIA document: Save your work temporarily Create a product class root (PRC) and product in ENOVIA Send the ENOVIA document to CATIA Insert the components (Insert -> Existing Component) containing the work you saved temporarily above Save your work in ENOVIA. For more information, see the CATIA / ENOVIA Interoperability User's Guide.

133 Page 133 Taking Advantage of ENOVIA LCA Capabilities 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.

134 Page 134 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.

141 Page 141 Design Settings The Design tab contains one category of options: Default colors. 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.

142 Page 142 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 checked. 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:

143 Page 143 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. 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:

144 Page 144 To generate this drawing, you need to define the midship position (see below). By default, the option is Asymmetrical. 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 xcoordinates) 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.

145 Page 145 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 are cleared, and Apply 3D specifications is selected.

146 Page 146 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 option to take all stylesheets into account and choose the format of your output data when interactively generating your offset data. By default, this option is cleared and only XML files will be generated.
