Which Cut command option wraps a sketch profile across a bend in the folded model?

Answer: Cut Across Bend

Cut Across Bend maps the profile across the bend region so that the cut follows the bent geometry.

What is the usual workflow for adding a feature that must span a bend in the folded model?

Answer: Unfold the bend, add the feature, then Refold

Unfold temporarily flattens selected bends so features can be added, and Refold restores the folded state with the feature kept.

What sketch geometry does the Punch Tool command use to locate punch features?

Answer: Sketch center points on the face

The Punch Tool places the iFeature at center points in a sketch on the sheet metal face.

Which bend relief shape removes no material and lets the sheet tear at the end of the bend?

Answer: Tear

Tear relief rips the material at the bend ends without removing any material.

With a K-factor of 0.44, where is the neutral axis located?

Answer: 44% of the thickness from the inside face of the bend

The K-factor is the ratio of the neutral-axis distance from the inside surface to the material thickness.

Where do you change the base face, alignment, and punch direction of an existing flat pattern?

Answer: Edit Flat Pattern Definition

Edit Flat Pattern Definition controls the flat pattern's orientation, base face, and punch direction.
