ACP Sheet Metal Design 3 — Questions and Answers
Question 1: Which of these is NOT an unfold rule type in the Inventor Style and Standard Editor?
- Custom Equation
- Neutral Spline (Correct answer)
- Bend Table
- Linear
Correct answer: Neutral Spline
Inventor unfold rules can be Linear (K-factor), Bend Table, or Custom Equation, and there is no Neutral Spline type.
Question 2: Which Cut command option wraps a sketch profile across a bend in the folded model?
- Cut Normal
- Through All
- Cut Across Bend (Correct answer)
- Unfold Cut
Correct answer: Cut Across Bend
Cut Across Bend maps the profile across the bend region so that the cut follows the bent geometry.
Question 3: What is the usual workflow for adding a feature that must span a bend in the folded model?
- Edit the flat pattern and add the feature there only
- Convert the part back to a standard part
- Suppress the bend and rebuild it later
- Unfold the bend, add the feature, then Refold (Correct answer)
Correct 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.
Question 4: What sketch geometry does the Punch Tool command use to locate punch features?
- Work planes normal to the face
- Sketch center points on the face (Correct answer)
- Construction lines along bend edges
- Projected cut edges
Correct answer: Sketch center points on the face
The Punch Tool places the iFeature at center points in a sketch on the sheet metal face.
Question 5: Which bend relief shape removes no material and lets the sheet tear at the end of the bend?
- Square
- Straight
- Round
- Tear (Correct answer)
Correct answer: Tear
Tear relief rips the material at the bend ends without removing any material.
Question 6: With a K-factor of 0.44, where is the neutral axis located?
- 44% along the length of the bend
- At 0.44 times the bend radius
- 44% of the thickness from the inside face of the bend (Correct answer)
- 44% of the thickness from the outside face of the bend
Correct 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.
Question 7: Where do you change the base face, alignment, and punch direction of an existing flat pattern?
- Sheet Metal Defaults
- iProperties
- Edit Flat Pattern Definition (Correct answer)
- Document Settings
Correct answer: Edit Flat Pattern Definition
Edit Flat Pattern Definition controls the flat pattern's orientation, base face, and punch direction.
