Solid Modeling Theory concepts
 
 
 

Become familiar with the concepts of solid model data types to understand how geometric and topological data work together to form a complete model.

How does it work

The following is an example of a solid model of a cube which has six surfaces (faces) labeled S1 to S6 which form the geometrical and topological information required to define it as a solid model. Each of the surfaces has a loop set, but in this case each surface has only one loop. The loop for S1 has four edges and four vertices.

The edges are used to connect two loops from adjacent surfaces. The vertices are used to connect two or more edges.

This solid box consists of six surfaces, twelve edges, and eight vertices that form the geometrical and topological information required to define it as a solid model. For example, if a hole is placed in the box through S1 and S6, S1 and S6 would each have a loop set containing two loops.
