CSWP Evaluation Structure 3 — Questions and Answers
Question 1: In SolidWorks Simulation, which result plot type is most useful for identifying where a structural part is most likely to fail under ductile material conditions?
- Displacement (URES)
- von Mises stress (VON) (Correct answer)
- Strain energy density
- Resultant reaction force
Correct answer: von Mises stress (VON)
The von Mises stress plot is the standard failure criterion for ductile materials and is used to compare against yield strength for factor of safety analysis.
Question 2: When using the SolidWorks Evaluate tab's 'Check' tool on a part, what type of errors does it detect?
- Missing mates in assemblies
- Geometry errors such as invalid faces and zero-thickness geometry (Correct answer)
- Missing material definitions
- Underdefined sketch relations
Correct answer: Geometry errors such as invalid faces and zero-thickness geometry
The Geometry Check tool identifies solid modeling errors like invalid faces, short edges, and zero-thickness geometry that could prevent downstream operations.
Question 3: What does a 'Rebuild Error' (red traffic light) in the FeatureManager Design Tree indicate during part evaluation?
- The part file is corrupted and must be recreated
- A feature failed to regenerate due to a geometric or reference error (Correct answer)
- The mass properties are out of date
- A mate is over-defined
Correct answer: A feature failed to regenerate due to a geometric or reference error
A red traffic light icon means SolidWorks could not successfully rebuild that feature, often due to missing references, invalid geometry, or conflicting constraints.
Question 4: When evaluating draft angles using the Draft Analysis tool, what color is applied to faces with sufficient positive draft?
- Red
- Yellow
- Green (Correct answer)
- Blue
Correct answer: Green
By default, SolidWorks Draft Analysis colors faces green when they have positive draft greater than or equal to the specified draft angle.
Question 5: In the context of CSWP evaluation, what does 'Zebra Stripes' analysis reveal about a surface?
- Material grain direction
- Curvature continuity and surface quality (Correct answer)
- Wall thickness uniformity
- Interference between adjacent faces
Correct answer: Curvature continuity and surface quality
Zebra Stripes simulate reflective light stripes on a surface to reveal curvature continuity (G1, G2) and surface irregularities not visible in normal shading.
Question 6: A CSWP candidate needs to verify that all walls in a plastic part are within a specified thickness range. Which SolidWorks Evaluate tool is designed for this task?
- Interference Detection
- Thickness Analysis (Correct answer)
- Draft Analysis
- Curvature Analysis
Correct answer: Thickness Analysis
Thickness Analysis (under Evaluate) color-maps wall thicknesses across the model to identify regions that are too thin or too thick.
Question 7: When evaluating an assembly's Bill of Materials, what is the difference between 'Top-Level Only' and 'Parts Only' BOM types?
- Top-Level Only lists subassemblies as single items; Parts Only lists every individual component (Correct answer)
- Top-Level Only includes hardware; Parts Only excludes it
- Top-Level Only shows quantities; Parts Only shows descriptions only
- There is no functional difference between these BOM types
Correct answer: Top-Level Only lists subassemblies as single items; Parts Only lists every individual component
Top-Level Only treats subassemblies as single line items, while Parts Only dissolves all subassemblies and lists each individual part separately.
