Surface Modeling Flashcards

Which command makes a surface that extends from a selected model edge in the Normal, Tangent, or Vector direction?

Answer: Ruled Surface

Ruled Surface creates a surface from edges using Normal, Tangent, or Vector types.

A designer needs to swap the top face of a solid for an imported freeform surface. Which command is best?

Answer: Replace Face

Replace Face swaps one or more solid faces for a surface, and the solid is extended or trimmed to meet it.

What does the Heal option do in the Delete Face command?

Answer: Fills the gap left by the deleted face by extending the adjacent faces

Heal extends the surrounding faces until they meet, closing the void left by the removed face.

Which command can add material to a solid or remove it, using surfaces as the boundaries?

Answer: Sculpt

Sculpt adds or removes solid material within regions bounded by selected surfaces or work planes.

In the Extend command, how is the Stretch option different from Extend?

Answer: Stretch carries the edge curvature into the extension, while Extend continues adjacent edges along straight lines

Extend continues adjacent edges in a straight line, while Stretch keeps curvature in the extended area.

Which tool removes part of a surface that lies on one side of a cutting tool such as another surface or a work plane?

Answer: Trim Surface

Trim Surface uses a cutting edge, surface, or plane to remove the selected region of a surface.

Which analysis shows reflection stripes across faces to check tangent and curvature continuity?

Answer: Zebra analysis

Zebra analysis displays striped reflections, and breaks or kinks in the stripes reveal continuity problems.
