1. When you place a frame member, which option rotates the profile around the skeleton edge? → Rotation angle
2. In a Loft, what is the purpose of adding Point Mapping on the Transition tab? → To control which points on each section connect, reducing unwanted twist
3. How can model weld symbols be added to a drawing view automatically? → Use Retrieve Model Annotations on the view
4. Which tool removes part of a surface that lies on one side of a cutting tool such as another surface or a work plane? → Trim Surface
5. Where does an assembly feature, such as an extrude cut made in the assembly environment, exist? → Only in the assembly file
6. What does iLogic Design Copy do? → Copies a set of iLogic-driven files, with their rules and references, to a new location
7. Where do you change the base face, alignment, and punch direction of an existing flat pattern? → Edit Flat Pattern Definition
8. Which dimension type displays only a value at each feature, measured from a single origin, without dimension lines between features? → Ordinate
9. Which motion constraint is used to simulate a rack and pinion? → Rotation-Translation
10. A designer wants an iLogic rule to run automatically every time the document is saved. What should they configure? → An Event Trigger on Before Save Document
11. When authoring a custom iPart, what is the purpose of a custom parameter column? → It lets the user type any value for that parameter when placing the member
12. What is the recommended way to customize a standard bolt family supplied by Autodesk? → Copy the family to a read/write library and edit the copy
13. What does the Stitch tolerance value control? → The largest gap between edges that can still be joined
14. Which command on the Manage tab lets you add your own part (for example a custom pin) to a read/write Content Center library? → Publish Part
15. What file extension does an iPart factory file use in Autodesk Inventor? → .ipt
16. Where do you change the default balloon shape, for example from circular to hexagonal, for all new balloons? → Balloon style in the Style and Standard Editor
17. Which command explicitly sets the face that controls flat pattern orientation and punch direction? → A-Side Definition
18. Turning off the Enabled option for a component causes it to: → Display translucent and become unselectable
19. When using Copy Components, choosing Reuse for a component will: → Place another occurrence of the existing file
20. Which weld type adds no 3D solid geometry but can still be documented in drawings? → Cosmetic weld
21. How does Inventor calculate weld bead mass for BOM purposes? → It calculates from the weld bead geometry and selected filler material density
22. How can a designer temporarily view the weldment as it looked before machining features? → Drag the End of Features marker above the Machining folder
23. In Inventor's Dynamic Simulation, which joint type replicates the behavior of a ball-and-socket connection with three rotational degrees of freedom? → Ball
24. Which style controls which dimension, text, and layer styles are applied by default to each new annotation type? → Object Defaults
25. 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
26. Which Content Center parameter commonly holds a frame member's length and is often used for BOM base quantity? → G_L
27. What does G1 continuity mean between two surfaces? → The surfaces touch and share tangency at the joint
28. What happens to a Content Center part placed As Standard? → It is saved automatically to the Content Center Files folder
29. In the rule editor, which option keeps a rule from running when one of its referenced parameters changes? → Don't Run Automatically
30. 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
