ACP Sheet Metal Design 4 — Questions and Answers
Question 1: Which Flange width extents option makes a flange of a set length centered on the selected edge?
- Edge
- From To
- Offset
- Width (with Centered) (Correct answer)
Correct answer: Width (with Centered)
The Width extent with the Centered option makes a flange of a fixed width centered on the edge.
Question 2: When you use the Fold command, what must the sketch line do?
- Lie on the sheet metal face and reach its edges (Correct answer)
- Be drawn on a work plane offset from the part
- Be a closed profile
- Be drawn on the flat pattern
Correct answer: Lie on the sheet metal face and reach its edges
Fold bends the face along a sketch line that lies on the face and ends on its edges.
Question 3: A shelled box was converted to sheet metal but cannot be flattened because it is fully closed. Which command adds the needed gap?
- Rip (Correct answer)
- Unfold
- Corner Seam
- Cut
Correct answer: Rip
Rip makes a gap (single point, point to point, or face extents) so a closed shape can be unfolded.
Question 4: A common reason a flat pattern fails to generate in a sheet metal part is:
- The part has more than four bends
- The part does not have a uniform thickness (Correct answer)
- The part has a custom appearance
- The part uses the Default sheet metal rule
Correct answer: The part does not have a uniform thickness
Unfolding needs a uniform thickness, so features that change the thickness make the flat pattern fail.
Question 5: Which command adds manufacturing mark lines that are not bends and that carry into the flat pattern and DXF export?
- Split
- Cosmetic Centerline (Correct answer)
- Bend Line
- Construction Line
Correct answer: Cosmetic Centerline
Cosmetic centerlines add reference marks, such as scribe lines, that appear in the flat pattern and in exports.
Question 6: In an Inventor drawing, which annotation lists each bend's ID, direction, angle, and radius in a table?
- Parts List
- Hole Table
- Revision Table
- Bend Table (Correct answer)
Correct answer: Bend Table
The Bend Table shows bend data, such as direction, angle, and radius, for flat pattern views.
Question 7: In the Inventor Default sheet metal rule, what is the default bend radius set to?
- Thickness (Correct answer)
- 0.5 mm
- 2 x Thickness
- The K-factor value
Correct answer: Thickness
The Default rule sets the bend radius equal to the Thickness parameter.
