Surface Modeling Flashcards

By default, how does Inventor display surface bodies in the graphics window?

Answer: Translucent

Surfaces show as translucent by default so you can tell them apart from solids, and this can be changed per surface.

Which command copies faces or bodies from a source body as a surface or solid, with an option to keep them associative?

Answer: Copy Object

Copy Object duplicates selected faces or bodies as a surface, composite, or solid, and the copy can stay linked to its source.

Which condition must be true before Sculpt can create a solid from surfaces alone?

Answer: The surfaces must fully enclose a volume

Sculpt needs the selected surfaces, possibly with extensions, to bound a closed region for the new solid.

Which statement about Trim Surface is correct?

Answer: It works only on surfaces, not on solid faces

Trim Surface edits surface bodies, while solid faces are changed with tools like Split or Delete Face.

What is the main purpose of Draft Analysis on a surfaced part?

Answer: To check whether faces have enough draft angle for the mold pull direction

Draft Analysis colors faces by draft angle relative to a pull direction to check moldability.

A Boundary Patch edge set to Contact gives which kind of continuity?

Answer: G0 position continuity only

Contact makes the patch touch the adjacent edge without matching tangency or curvature.

In the Freeform environment, what does the Edit Form command let you do?

Answer: Move, rotate, or scale faces, edges, and points of a T-spline body

Edit Form gives a manipulator for moving T-spline faces, edges, and vertices to reshape the body.
