Which term describes a modeling approach that analyzes the geometry's volume rather than just its edges?

• A. Model
• B. Scale Model
• C. Solid Modeling
• D. Geometric Constraint

Answer: (C)

Focusing on volume rather than just edges is the hallmark of solid modeling. This approach creates a true 3D region that encloses material, not merely a set of interconnected lines or surface skins. Because the geometry defines enclosed space, you can compute physical properties like volume, mass, center of gravity, and moments of inertia, and you can perform solid operations (such as adding or subtracting volumes) to simulate how parts fit and interact in real life. A generic model doesn’t specify volume by itself; a scale model is only a smaller or larger physical replica and isn’t about computational volume analysis; geometric constraints describe relationships between features but don’t inherently define a filled volume for analysis.
