What is 3D Solid Modeling?

3D solid modeling is a form of computer-aided design (CAD) that represents the solid volume of an object. Unlike wireframe or surface modeling, solid models define both the surface and interior of an object, allowing for realistic visualizations, accurate calculations of properties like volume and mass, and interference checking. It's commonly used in engineering, manufacturing, architecture, and product design to create and analyze designs before physical prototypes are built.
