CSWP Evaluation Structure 2 — Questions and Answers
Question 1: When performing interference detection on an assembly, which result indicates a valid press-fit condition?
- Interference is listed but marked as non-interfering (Correct answer)
- Interference is listed and shown in red
- No interference volumes are generated
- Coincident faces are highlighted in yellow
Correct answer: Interference is listed but marked as non-interfering
SolidWorks allows you to mark specific interferences as non-interfering to represent intended press-fit or shrink-fit conditions.
Question 2: In SolidWorks, which tool would you use to measure the minimum distance between two non-touching components in an assembly?
- Interference Detection
- Measure tool (Correct answer)
- Collision Detection
- Section View
Correct answer: Measure tool
The Measure tool can report the minimum distance, maximum distance, and center-to-center distance between selected entities.
Question 3: What does the 'Treat coincident surfaces as interferences' option do in Interference Detection?
- Flags shared faces between adjacent parts as interference (Correct answer)
- Ignores all touching surfaces
- Highlights only overlapping volumes
- Disables detection for mated faces
Correct answer: Flags shared faces between adjacent parts as interference
Enabling this option causes SolidWorks to report coincident (touching) surfaces as interferences, useful for identifying improper contact conditions.
Question 4: Which Mass Properties value would change if you alter the material density of a part in an assembly without changing its geometry?
- Volume
- Surface Area
- Mass (Correct answer)
- Center of Mass location
Correct answer: Mass
Mass = Density × Volume; changing density directly changes mass while volume and surface area remain geometry-dependent.
Question 5: When evaluating a CSWP part model, the moment of inertia is reported relative to which default coordinate system?
- The part's center of mass
- The world origin (0,0,0)
- The output coordinate system (Correct answer)
- The first sketch origin
Correct answer: The output coordinate system
SolidWorks reports moments of inertia relative to the output coordinate system, which defaults to the part origin unless overridden.
Question 6: What is the purpose of the 'Show volumes' option in Interference Detection?
- Renders translucent parts for visual clarity
- Displays the geometric volume of each interfering region (Correct answer)
- Calculates total overlapping mass
- Exports interference data to a report
Correct answer: Displays the geometric volume of each interfering region
The Show Volumes option visually highlights the volumetric overlap regions between interfering components in the graphics area.
Question 7: During CSWP structural evaluation, if you apply a fixed constraint and a force load in SolidWorks Simulation, what does the factor of safety (FOS) represent?
- The ratio of material yield strength to maximum von Mises stress (Correct answer)
- The ratio of applied force to material density
- The percentage of part volume under stress
- The displacement magnitude at maximum load
Correct answer: The ratio of material yield strength to maximum von Mises stress
FOS = Yield Strength / Maximum von Mises Stress; values above 1 indicate the part will not yield under the applied load.
