ACP Sheet Metal Design 5 — Questions and Answers
Question 1: How can a parts list automatically show the flat blank size of a sheet metal part?
- Measure the flat pattern manually and type the values
- Use the Sheet Metal Length and Sheet Metal Width iProperties (Correct answer)
- Use the Mass iProperty
- Add the K-factor as a custom column
Correct answer: Use the Sheet Metal Length and Sheet Metal Width iProperties
Inventor provides flat pattern extent properties that can be shown in parts lists and title blocks.
Question 2: What sketch profile does Contour Flange need, compared with the Face command?
- Both need open profiles
- Both need closed profiles
- Contour Flange uses a closed profile, Face uses an open profile
- Contour Flange uses an open profile, Face uses a closed profile (Correct answer)
Correct answer: Contour Flange uses an open profile, Face uses a closed profile
Contour Flange adds thickness to an open profile, and Face extrudes a closed profile to the sheet thickness.
Question 3: What happens to the sharp corners in a Contour Flange sketch?
- You must add a sketch fillet at each corner first
- Inventor automatically replaces them with bends using the rule's bend radius (Correct answer)
- They are converted to corner seams
- They stay sharp and the flat pattern fails
Correct answer: Inventor automatically replaces them with bends using the rule's bend radius
Contour Flange automatically adds bends at the sketch corners using the active bend radius.
Question 4: Which command explicitly sets the face that controls flat pattern orientation and punch direction?
- Sheet Metal Defaults
- A-Side Definition (Correct answer)
- Edit Flat Pattern Definition
- Make Components
Correct answer: A-Side Definition
A-Side Definition sets the face Inventor uses as the A side, which controls the punch direction and flat pattern orientation.
Question 5: Your shop gives you measured bend deduction values for each thickness, radius, and angle. Which unfold rule type should you use?
- Default K-factor
- Linear
- Custom Equation
- Bend Table (Correct answer)
Correct answer: Bend Table
A Bend Table unfold rule looks up measured bend allowance or deduction values from a table.
Question 6: What is the K-factor value in Inventor's Default unfold rule?
- 0.44 (Correct answer)
- 0.33
- 0.25
- 0.50
Correct answer: 0.44
The Default_KFactor unfold rule in Inventor uses a K-factor of 0.44.
Question 7: In the Corner Seam command, which overlap option makes one face extend over the edge of the other?
- Overlap (Correct answer)
- Symmetric Gap
- Maximum Gap Distance
- Butt
Correct answer: Overlap
Overlap makes one face cover the other face's edge, while Symmetric Gap leaves an equal gap between both faces.
