CSWE CSWE Surface Modeling & Complex Geometry 2 — Questions and Answers
Question 1: What is the purpose of the 'Offset Surface' tool in SOLIDWORKS?
- Creates a parallel copy of a selected surface or solid face at a specified distance (Correct answer)
- Wraps a planar sketch onto a curved surface
- Extrudes a surface body into a solid
- Mirrors a surface about an assembly plane
Correct answer: Creates a parallel copy of a selected surface or solid face at a specified distance
Offset Surface generates a new surface body offset from a reference surface or solid face by a constant distance, preserving the original geometry's shape.
Question 2: When applying a 'Swept Surface' in SOLIDWORKS, what role does a 'Guide Curve' play?
- It defines the cross-section profile shape
- It constrains how the profile scales and orients as it travels along the path (Correct answer)
- It sets the start and end tangency conditions
- It determines the surface color mapping
Correct answer: It constrains how the profile scales and orients as it travels along the path
Guide curves in a Swept Surface control how the cross-section profile changes shape, scale, or twist as it sweeps along the path, enabling complex tapered or twisted geometry.
Question 3: Which SOLIDWORKS tool wraps a 2D sketch or image onto a non-planar 3D surface as embossed, debossed, or scored geometry?
- Project Curve
- Wrap Feature (Correct answer)
- Deform Feature
- Imprint Surface
Correct answer: Wrap Feature
The Wrap feature projects a 2D sketch onto a cylindrical, conical, or NURBS surface to create raised (emboss), recessed (deboss), or scribed (scribe) 3D geometry.
Question 4: What is the primary use case for SOLIDWORKS 'Deform' feature's 'Surface Push' option?
- Creating draft angles on injection-molded parts
- Locally deforming a surface or solid by pushing a tool body into it to create organic or impact-shaped geometry (Correct answer)
- Offsetting an entire surface body by a variable amount
- Generating parting lines for mold tooling
Correct answer: Locally deforming a surface or solid by pushing a tool body into it to create organic or impact-shaped geometry
The Surface Push deform option uses a tool body shape to locally indent or bulge target geometry, ideal for creating dents, indentations, or organic compound curves.
Question 5: In SOLIDWORKS, what does the 'Delete Face' feature do when used with the 'Delete and Patch' option?
- Removes the selected face and heals the gap by extending adjacent faces to fill the void (Correct answer)
- Deletes the face and leaves an open edge loop in the solid
- Converts the deleted face into a separate surface body
- Removes a face and replaces it with a planar fill
Correct answer: Removes the selected face and heals the gap by extending adjacent faces to fill the void
Delete and Patch removes the target face and automatically extends neighboring faces to close the resulting gap, preserving the solid or surface as a single body.
Question 6: Which SOLIDWORKS surface analysis tool maps the rate of change of curvature across a face using a color gradient to identify flat, convex, and concave regions?
- Zebra Stripes
- Draft Analysis
- Curvature (Correct answer)
- Deviation Analysis
Correct answer: Curvature
The Curvature display colors faces based on Gaussian or mean curvature values, using a spectrum from cool (low/flat) to warm (high/curved) to reveal surface shape characteristics.
