Surface Modeling Flashcards

What is the fundamental difference between a surface body and a solid body in SolidWorks?

Answer: A surface body has zero thickness, while a solid body has volume

Surface bodies are infinitely thin geometric shells with no volume, while solid bodies are fully enclosed with mass and volume.

Which SolidWorks feature creates a surface by sweeping a 2D profile along a defined path?

Answer: Swept Surface

Swept Surface moves a cross-sectional profile along a guide path to generate the surface geometry.

What does the Knit Surface feature do in SolidWorks?

Answer: Combines multiple surface bodies into one surface body

Knit Surface merges two or more adjacent or overlapping surface bodies into a single unified surface body.

Which surface feature in SolidWorks creates geometry by blending between two or more profiles located at different positions?

Answer: Loft Surface

Loft Surface generates a smooth surface by transitioning between two or more profile sketches placed at different locations.

What does the Offset Surface feature do in SolidWorks?

Answer: Creates a copy of a surface at a specified distance from the original

Offset Surface duplicates an existing surface and positions it at a user-defined perpendicular distance from the original.

Which SolidWorks surface tool is used to repair or close open gaps and holes within a surface body?

Answer: Fill Surface

Fill Surface generates a patch surface to close openings, gaps, or holes bounded by surface edges.

What is a Ruled Surface in SolidWorks?

Answer: A surface generated by extruding straight lines from an edge

A Ruled Surface creates surface geometry by projecting straight line segments outward from a selected edge or curve.
