4 1. PARAMETERS Parameters are essentially more intelligent dimensions; you can create parameters on the fly, or by using the parameters dialogue box. Rather than entering numbers for dimensions you could enter a parameter called length, or width. You can also add equations and formulas into parameters. Parameters can be used in single parts, and assemblies, and can be used in conjunction with I Parts. Teaching Time = 1 hour 2. I PARTS I Parts are a method of creating table driven parts. These work similar to the parts that can be accessed from the Inventor Content Centre. They are ideal for creating standard components but are of differing sizes and possibly have different features depending on their size. For example, if you made motors, the external box would come in different sizes depending on its power and may also have different openings to fit other components. This could be achieved by using I Parts. You would create the basic size and then by using an I Part table you could change the sizes and have different holes or cuts be displayed in the different sizes. Teaching Time = 3 Hours 3. I ASSEMBLIES I Assemblies are similar to I Parts, but are used within the assembly environment. These can show different configurations of an assembly as well as different sizes of the parts within (when used in conjunction with I Parts). For example, if you made conveyor s these could be different lengths and widths, they could also have different motors attached to them or even be in different materials. Teaching Time = 2 hours PAGE: 3 OF 30

5 4. I MATES I mates are a way of automatically assembling components in an assembly. The assembly constraints are applied in the part file, and then when that part file is inserted into an assembly, any I mates with the same names will constrain together. This is similar to the way that the auto drop functionality within the Inventor Content Centre works. For example, within your motors (which come in different sizes) there are various push buttons that are inserted into holes within the external box. By using I Mates when you inserted the push button into the motor assembly it could be made to automatically insert. It can also be made to insert the button into every coinciding hole. Teaching Time = 1 Hour 5. I FEATURES I Features are a tool that enables the user to simplify the creation of standard sketches and features. These work in a similar manner to the sheet metal punches that exist within Inventor For example, in your motor design you create various openings that are used to insert push buttons. These openings are of different sizes, but of the same shape. This could be done via I Features, where you could insert the feature onto the desired face, enter the dimensions. It would then create the opening for you Teaching Time = 1 Hour PAGE: 4 OF 30

6 6. SURFACING TOOLS INCLUDING SCULPT, STITCH AND BOUNDARY PATCH Surfacing tools can be used to create solid geometry from existing surfaces or imported data. You may need to fill in the gaps on imported data, or create additional surfaces to help you create a solid model For example, you have received a file from another 3D CAD package. This data comes in as imported surfaces. Using the sculpt tool you could create a solid by filling in the surfaces. Fig Ref:1 Collecting or Surfaces and Sculpted Model Teaching Time = 1 Hour 7. COPY OBJECT Copy object allows you to reference other data in other files by copying faces or surfaces through into another part. These can then be used to create more geometry in the new part file. For example, you have a car body panel that you need to create jigs and fixtures for. You could copy the data from the panel into the new fixture part file, and then by using standard Inventor tools you could cut geometry so the panel would fit. If the data in the car body panel was updated the fixture would automatically update. Teaching Time = 1 Hour PAGE: 5 OF 30

7 8. LEVELS OF DETAIL Levels of details are a method of streamlining your assemblies to show different parts in different levels of detail. This will have the effect of speeding up your PC, as the files that have been suppressed are not loaded into memory. You can also create drawings of the different levels of detail therefore giving the capability to show the same assembly file in a drawing with different parts visible. For example, if you had a paper rolling machine, that has parts. Especially on older PC s this may take a long time to load and work on. By using levels of details you could open the assembly with a level of detail and it will not load the suppressed parts making it quicker load and a lot easier to work with. Teaching time = 0.5 hours 9. SHRINKWRAP Shrinkwrap is an addition to the levels of detail functionality giving the ability to turn a full assembly into one single part. This could be used to lower the amount of parts that are loaded into memory; it can also be used to maintain your intellectual rights to the assemblies by removing the ability of taking it apart even if they have the electronic file. For example, you need to send the electronic file of your paper rolling machine to a potential customer. This would be a large file to send and if you did send the full assembly it could be disassembled to view the internal components. By using Shrinkwrap it would be one file, that would be a lot smaller than the full assembly and the internal components could not be viewed within Inventor or design review. Teaching Time = 0.5 hours PAGE: 6 OF 30

8 10. CONTENT CENTRE EDITING AND PUBLISHING Within Inventor there is the content centre which is a library of hundreds of thousands standard parts, which are driven by standards such as ISO, ANSI and DIN. You can edit these to use your own company part numbers and you can also publish your own parts into it, for use by other members of the organisation. This functionality can be made even more productive if used in conjunction with I Parts and I Assemblies For example, you assemble various motors, and have several company specific components that go into this assembly. After these have been modelled they could be published to the content centre so other designers could use the same parts. You could also edit for example the ISO 4016 bolt to use your own company part numbers rather than the standard information that Inventor provides. Teaching Time = 2 hours PAGE: 7 OF 30

9 11. FRAME GENERATOR The frame generator allows you to place standard or custom profiles along or between existing geometry; these can then have treatments applied to them such as notches and mitres. These frames are then adaptive to the existing geometry, and will resize accordingly. For example, you are a steel fabrication company and assemble various profiles such as I Beams and square sections to create a steel structure for use in the building environment. You could model a basic structure using normal Inventor functions such as extrude and then attach the steel profiles to the edges. You can also create your own company specific custom profiles that may be used in curtain walls or window assemblies. This functionality could also be used for various other things such a jig and fixture design as well as furniture design. Fig Ref:2 Full Frame Generator Example and Mitre Corner Teaching Time 3hrs PAGE: 8 OF 30

10 12. ADAPTIVITY Adaptivity can be looked at two different ways; you can create adaptivity by using top down design in the assembly environment. This is by using the create component functionality, which by utilising the project geometry tool you be recycle the information that exists within other parts to create new parts. For example, if you created LCD screens for laptops, by reusing the information from the lid of the laptop you could project and offset geometry and then create the screen. This means that the screen would be adaptive to the lid, therefore if the lid changed size, the LCD screen would adapt to suit. The other method of using adaptivity within Inventor is by adding adaptive features into both the part file and the assembly file. When you then place the part file into the assembly and constrain it, it will adapt to fit around its environment. For example, if you had a square plate with two bosses on it, you are then going to create a link arm that goes between the two bosses. If this link arm was an adaptive part it would grow or shrink to suit the part it was attached to. Teaching Time = 2 hours PAGE: 9 OF 30

11 13. POSITIONAL REPRESENTATIONS Positional representations are a method of creating parts within an assembly which can exist at different positions within the assembly. This can then be displayed within the assembly at those different positions; you will also be able to create overlay views within the drawing file which display these different positions. For example, if you had a hydraulic ram assembly, the position of the piston could be displayed potentially open or closed or anywhere in between. Using positional representation you could show the piston in the different positions and then create the views from it Fig Ref:3 An Example of Overlay Views Teaching time = 1 Hour 14. EXCEL DRIVEN PARTS These are similar to parameters, and can also be used within I Parts and I Assemblies. You can link an Excel spreadsheet into the parameters box, utilising the powerful tools within Microsoft Excel For example, within your motor design, some of the calculations required are quite complicated. You could create or already have a spreadsheet, then link the data into Inventor parameters. Then if the Excel spreadsheet was updated it would automatically update the parts that were derived from it. Teaching Time = 1 Hour PAGE: 10 OF 30

12 15. SKELETAL MODELLING & SKETCH BLOCKS Skeletal Modelling is a method of building assemblies from simple sketches. For example, if you made bike frames you could create a very basic sketch, and then create the tubular frames on top of the sketch. This could then adapt if the sketch was changed. Fig Ref:4 Skeleton Sketch and Finished Assembly Sketch blocks are similar to skeletal modelling, but you can then test the movement of the assembly by using the sketches, but this is within the part environment. You could then extrude and revolve etc to create the geometry and separate these out using multi body parts Fig Ref:5 Example of Sketch Blocks Teaching Time = 2 Hours PAGE: 11 OF 30

13 16. 3D SKETCHING 3D sketching is similar to 2D sketching, but utilising the 3rd direction, this is ideal for creating pipe work within Inventor, if you do not have Inventor Routed Systems. Fig Ref:6 3D Sketching & Finished Pipe Work Teaching Time = 0.5 hours 17. BILL OF MATERIALS (BOM) STRUCTURE There are various aspects of BOM structure which can be misleading such as reference parts and phantom parts, and they can affect the parts lists that appear in the drawing. Teaching Time = 0.5 hours PAGE: 12 OF 30

14 18. STYLE LIBRARIES This module would show the correct use of the style libraries to maintain your company standard for various things such as dimension and text styles, how to add your own custom materials and colours for use throughout the company. This could also show how to create multiple standards within your library, in order to let you have your clients specific standards built into your own. This will also show how to correctly update and save the libraries so they will appear on all of the machines that have an Inventor licence. Teaching Time = 2 hours 19. MULTI BODY PARTS Multi body parts are a method of creating an assembly file from a single part file. For example if you have created as a single part file a hand held torch, this would consist of various extrusions, sweeps and revolves as well as other features. By utilising multi body parts you could separate the handle, lens and body to create three separate part files. Teaching Time = 2 Hours PAGE: 13 OF 30

15 20. PLASTIC PART DESIGN There are many features within Inventor to help create plastic part features, such as Rests, grills and snap fits, although they can be used within normal part design. Fig Ref:7 Some Examples of Plastic Pat Features Teaching Time = 2 Hours 21. CUSTOM USER COORDINATE SYSTEM (UCS) This module explains how to create a custom coordinate system within a part file. This can be used to help you create geometry; a custom UCS contains work planes, axis and points making it easier to create complicated work features. You can also create assembly constraints by using the custom UCS, making it easier to constrain parts that contain complicated geometry. Teaching Time = 0.5 hours PAGE: 14 OF 30

16 22. PROJECT FILES Project files is how Inventor handles the files it used, whether this part or assembly files or the support files that Inventor needs to run. You can have multiple project files or if you are using Vault you would typically only have one. Project files are incredibly important to Inventor, and understanding these are imperative to getting more out of Inventor Teaching Time - 1 hour 23. CONTACT SETS Contact Sets are a method of simulating the contact between two or more parts within an assembly. In the following example you can see using normal constraints, the large plate will go through the blue box. By using contact sets when you constrain to something that is a contact set, it will move out of the way Fig Ref:8 Contact Sets Teaching Time 0.5 hours PAGE: 15 OF 30

17 24. VISUAL STYLES Visual styles are a feature introduced in 2011 and can help you show others in the organisation or to external customers a more realistic look and feel to your models. For example, if you make steel railings you could show within Inventor a 3D representation of your model, this could also be displayed as a shaded view on your 2D drawing. By utilising visual styles you could this railing with more realistic colours, and actually in an environment Fig Ref:9 - Normal Inventor Colours Fig Ref:10 Using Visual Styles Teaching Time = 1Hour PAGE: 16 OF 30

18 25. FUNCTIONAL DESIGN - DESIGN ACCELERATORS The functional design tools enable you to create complex geometry by entering size data. Before any geometry is created, you can verify whether the design meets requirements by performing calculations. The formulas used for the calculations are based on international standards, and they are fully documented in the Engineers Handbook. This allows you to override or ignore certain calculations when experience dictates. Functional design is split into three categories: Inventor Design Accelerators Inventor Design Calculators Using these tools with the Inventor Content Centre DESIGN ACCELERATORS There are several design accelerators in built into Autodesk Inventor, these include Bolted Connections, Gear Generators, Shaft Generator, Cam Generator and Spring Generators. The following pages give a brief example of the Design Accelerator Interface and calculation dialogue boxes. PAGE: 17 OF 30

25 26. DIRECT EDIT Direct Edit is a method of editing models no matter if they have been created inside of Inventor or is imported geometry. Direct Edit allows you to manipulate the models using direct tools and have the model update dynamically. Fig Ref:22 Example Showing the Direct Edit Tool Teaching Time = 1 Hour PLEASE NOTE: This module needs to be taught if you are choosing AnyCAD module PAGE: 24 OF 30

26 27. ANYCAD AnyCAD is integrated file interoperability technology that provides direct associative capabilities without the need for file translation. Imagine you are an Inventor house that works with a supplier that uses SolidWorks. You are designing a pedal assembly and one of the components that you use is being redesigned by your supplier. What version should you use? How can you both design in an open environment. The Inventor user inserts the SolidWorks component into their assembly. Along the way, changes are made to the SolidWorks model and are automatically updated in Inventor with FULL associativity. Not only are features changed on the model, but as intelligence is added to the SolidWorks model, it appears automatically in Inventor. This allows a seamless real-time design workflow that is open and transparent. The Inventor user can leverage the native SolidWorks model inside Inventor. Teaching Time = 1.5 hours PLEASE NOTE: If selecting this module you should also choose the Direct Edit Module PAGE: 25 OF 30

27 28. JOINTS Use joints to define and manage relationships, Joints are similar to assembly constraints but are more reality based than normal constraints, and can be easier to locate. Each joint type fully defines the location and motion of the selected components. You can select end, mid or centre point geometry to define a joint. You can also set motion limits with joints which are easier and more flexible than with constraints, which for example would only allow a shaft to move 50mm in either direction. Fig Ref:23 Example Showing the Joints Workflow Teaching Time = 1.5 Hours PAGE: 26 OF 30

28 29. SHAPE GENERATOR Shape Generator was introduced in the 2016 R2 Inventor release for subscription customers and offers a new approach when designing lightweight, structural efficient parts. The intelligent strategy provided by Shape Generator allows for the maximisation or part stiffness based on user defined constraints. This technology has been integrated into Inventor and is convenient, easy to use application enhancing the design experience. Shape Generator allows refinement of design as it produces a 3D mesh to help guide the user through the early stages of conceptual design. Fig Ref:24 Shape Generator Basic Workflow PAGE: 27 OF 30

29 30. 3D PDF EXPORT The long awaited 3D PDF Export facility has now been introduced to Inventor This new file format export allows the user to export 3D model views, Design View Representations, BOMs and even attach.step files for use in communication and collaboration. 3D PDFs can be viewed in Adobe Acrobat Reader and with the use of 3D navigation tools the end user can manipulate model views, display the model tree and view all components included in the 3D DPF. Utilise out of the box and create custom 3D PDFs to allow you to efficiently create and communicate your designs. Fig Ref:25 Export your design to 3D PDF PAGE: 28 OF 30
