Answer
Correct Answer: extrude
Explanation
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:
Activate PressPull and hover over the target face.Click to select the face; the normal direction previews.Drag or enter a numeric distance to extend (positive) or cut (negative).Accept to modify the model volume accordingly.Optionally fillet/chamfer resulting edges if needed.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
