Solidworks Surface Modeling 2 — Questions and Answers
Question 1: What is the purpose of the Trim Surface feature in SolidWorks?
- To add material to a surface edge
- To cut away portions of a surface using another surface or sketch (Correct answer)
- To combine two surfaces into one
- To project a curve onto a surface
Correct answer: To cut away portions of a surface using another surface or sketch
Trim Surface removes unwanted regions of a surface body using a trimming tool such as another surface, plane, or sketch.
Question 2: Which feature in SolidWorks lengthens a surface beyond its existing boundary edges?
- Knit Surface
- Extend Surface (Correct answer)
- Ruled Surface
- Offset Surface
Correct answer: Extend Surface
Extend Surface stretches the edges of a surface outward by a specified distance, enlarging the surface area.
Question 3: What does the Thicken feature do when applied to a surface body in SolidWorks?
- Increases the display resolution of the surface
- Converts the surface into a solid by adding material thickness (Correct answer)
- Applies a texture to the surface
- Copies the surface to a parallel position
Correct answer: Converts the surface into a solid by adding material thickness
Thicken adds a specified depth to a surface body, converting it into a solid with measurable volume and mass.
Question 4: What is a Boundary Surface in SolidWorks used for?
- Defining the outer shell of an assembly
- Creating a surface by fitting geometry through curves in two directions (Correct answer)
- Setting the simulation domain for flow analysis
- Defining material boundaries for FEA
Correct answer: Creating a surface by fitting geometry through curves in two directions
Boundary Surface creates a smooth surface using profiles defined in two perpendicular directions, offering more control than Loft Surface.
Question 5: Which operation converts a fully enclosed knitted surface body into a solid body in SolidWorks?
- Thicken
- Extrude Boss
- Create Solid from Surface
- Close Volume (via Knit with option enabled) (Correct answer)
Correct answer: Close Volume (via Knit with option enabled)
Enabling the 'Try to form solid' option in Knit Surface automatically converts a closed, watertight surface into a solid body.
Question 6: What does the Delete Face feature do in SolidWorks surface modeling?
- Removes a face from a solid or surface body (Correct answer)
- Hides a face from view without removing it
- Converts a face into a separate surface body
- Assigns a different material to a selected face
Correct answer: Removes a face from a solid or surface body
Delete Face removes one or more faces from a solid or surface body, with options to patch or fill the resulting opening.
Question 7: What is the function of the Replace Face feature in SolidWorks?
- Swaps a face's texture with another material
- Replaces selected faces of a solid with a new surface geometry (Correct answer)
- Mirrors a face across a symmetry plane
- Offsets a face to a new position
Correct answer: Replaces selected faces of a solid with a new surface geometry
Replace Face substitutes one or more existing faces on a solid body with a new surface, reshaping the solid to match the replacement geometry.
