ACP Advanced Part Modeling 2 — Questions and Answers
Question 1: When creating a Sweep in Inventor, which orientation option keeps the profile at a constant angle relative to the path as it travels?
- Guide Rail
- Parallel
- Guide Surface
- Path (Correct answer)
Correct answer: Path
The Path orientation holds the profile at a constant angle to the path along its entire length.
Question 2: Which Sweep type lets you control the profile's twist and scaling using an additional curve besides the path?
- Solid sweep
- Path only
- Path & Guide Rail (Correct answer)
- Path & Guide Surface
Correct answer: Path & Guide Rail
A guide rail controls the scaling and twist of the profile as it sweeps along the path.
Question 3: In a Loft, what is the purpose of adding Point Mapping on the Transition tab?
- To add extra sections automatically
- To convert the loft into a surface
- To set the loft's end tangency weight
- To control which points on each section connect, reducing unwanted twist (Correct answer)
Correct answer: To control which points on each section connect, reducing unwanted twist
Point mapping defines matching points between sections so the loft does not twist unexpectedly.
Question 4: Which Loft option uses a single centerline to control how sections blend, similar to a sweep path?
- Rails
- Area Loft
- Center Line (Correct answer)
- Closed Loop
Correct answer: Center Line
A Center Line loft keeps the sections normal to a centerline that guides the shape.
Question 5: What does an Area Loft allow you to control that a standard rail loft does not?
- The number of rails used
- The thickness of a surface loft
- The draft angle of the end faces
- The cross-sectional area at specific locations along the centerline (Correct answer)
Correct answer: The cross-sectional area at specific locations along the centerline
Area Loft lets you specify cross-sectional area values at placed sections along a centerline.
Question 6: When creating a Coil, which three parameters are paired in the Coil Size tab Type list?
- Diameter, Length, Angle
- Start, End, Transition
- Pitch, Taper, Thread class
- Pitch and Revolution, Revolution and Height, Pitch and Height, Spiral (Correct answer)
Correct answer: Pitch and Revolution, Revolution and Height, Pitch and Height, Spiral
The Coil Size types combine two of pitch, revolution and height, plus a Spiral option.
Question 7: On the Coil Ends tab, what does setting an end to Flat do?
- Removes the last revolution
- Cuts the coil with a planar face
- Adds a transition so the coil end becomes flat, like a compression spring end (Correct answer)
- Caps the coil profile with a surface
Correct answer: Adds a transition so the coil end becomes flat, like a compression spring end
Flat ends add transition and flat angles so the coil ends lie flat, as on a spring.
