1. What file extension does an iPart factory file use in Autodesk Inventor? → .ipt
2. How does Inventor calculate weld bead mass for BOM purposes? → It calculates from the weld bead geometry and selected filler material density
3. In Inventor's Dynamic Simulation, which joint type replicates the behavior of a ball-and-socket connection with three rotational degrees of freedom? → Ball
4. What is the function of a 'branch take-off' in Inventor's Tube & Pipe routing? → A junction where one pipe branches off from the main run at a defined angle
5. What does a 'frictionless' support boundary condition simulate in Inventor Nastran? → A surface constrained only in the direction normal to it, free to slide tangentially
6. In Inventor, which environment must be active to edit an existing pipe route segment? → Route Edit mode (double-click the route sub-assembly)
7. When publishing a custom fitting to the Tube & Pipe Content Center, which file must be correctly configured to define connection points? → The .ipt file with connector authoring (iPart or iAssembly factory)
8. What file format is commonly exported from Inventor for sheet metal CNC cutting? → DXF or DWG flat pattern
9. To edit an existing iPart table after it has been created, which method is correct? → Right-click the Table entry in the Model browser and select Edit Table
10. In Autodesk Inventor's Tube & Pipe environment, what is the first step to begin routing a new pipe run? → Use the Create Route command after defining a Tube & Pipe run in the assembly
11. What is the K-factor in Inventor sheet metal design? → A ratio that determines the position of the neutral axis in a bend
12. What is the Content Center in Autodesk Inventor? → A library of standard parts (fasteners, structural shapes, fittings) for use in assemblies
13. In Inventor's Dynamic Simulation, what must be done before exporting joint reaction forces to Inventor Nastran for FEA? → Run the dynamic simulation to generate force results, then use the Export to FEA command
14. How does Inventor handle corner relief in sheet metal parts? → It automatically adds corner relief to prevent material tearing at bend intersections
15. Which Inventor command is used to automatically route a pipe between two connection points along the shortest valid path? → Auto Route
16. What export formats are available for Inventor presentation animations? → AVI, WMV video formats and image sequences for creating assembly instruction materials
17. In an iAssembly, what is the 'factory file'? → The master .iam file that contains the iAssembly table with all member configurations
18. In Inventor's Dynamic Simulation, what is the function of an 'imposed motion' constraint? → It drives a joint at a prescribed velocity, acceleration, or position over time
19. Which feature in Autodesk Inventor allows creating geometry by revolving a profile around an axis? → Revolve
20. How does iLogic interact with iPart factories? → It can switch iPart rows based on rules, automating configuration selection
21. Which command is used to initiate the creation of an iPart in Autodesk Inventor? → Manage > Author > iPart Author
22. Which feature defines precise movement between assembly parts? → Joints
23. When placing iPart members in an assembly, which statement is true regarding mixing different members of the same iPart? → Multiple different members can be placed, each generating its own member file
24. In Inventor's Tube & Pipe module, what does 'nominal diameter' refer to? → A standardized size designation that approximates the pipe's inner diameter
25. How does the Stitch command work in Inventor surface modeling? → It joins multiple surface patches into a single quilted surface or solid
26. What file type stores a Tube & Pipe style definition in Autodesk Inventor? → .xml
27. What is a storyboard in Inventor presentations? → A timeline-based sequence of view states that creates assembly/disassembly animations
28. What does a 'rigid' route designation mean in Inventor's Tube & Pipe environment? → The route is solved using fixed orthogonal runs only
29. What is the primary purpose of an iPart in Autodesk Inventor? → To create a part with multiple configurations stored in a table
30. What is iLogic in Autodesk Inventor? → A rule-based design automation tool that captures and reuses engineering knowledge
