In modern 3D CAD (AutoCAD), the PressPull tool will do what to a planar face of a solid model along the face normal?

Introduction / Context:
PressPull is a fast, direct modeling tool used to modify solids by pushing or pulling faces. It streamlines common edits without requiring separate sketch profiles or dedicated feature dialogs.

Given Data / Assumptions:

• A planar face is selected on a solid body.
• The user drags the cursor in the face’s normal direction.
• Goal: understand the geometric result of PressPull.

Concept / Approach:
PressPull performs an “extrude-like” offset of the selected face along its normal. On solids, it changes the solid’s volume by extending or recessing the face; on regions, it extrudes. It does not inherently “spiral” or “taper” unless combined with additional features or commands.

Step-by-Step Solution:

Verification / Alternative check:
Use MASSPROP before and after to see a change in volume. Visual inspection should show the face moved parallel to its original plane.

Why Other Options Are Wrong:

• taper: Requires dedicated draft/taper tools or parameters; PressPull alone does not apply taper.
• spiral: Spiral is a path construct, not applicable to PressPull on a planar face.
• none of the above: PressPull clearly performs an extrude-like push/pull.

Common Pitfalls:
PressPull on nonplanar faces may not behave as expected. Also ensure you select the face (not an edge) to get the correct modification.

Final Answer:
extrude
