3D Wireframe Geometry and Surfaces
Wireframe is a generic term for points, lines, curves, and planes. If a wireframe is attached to sketch geometry, it is called a 2D wireframe (see Chapter 5). 3D wireframe geometry can be placed freely in space and is the foundation of describing a surface. (A surface is a two-dimensional structure spanned by wireframe geometry.) 3D wireframe geometry or surfaces are commonly referred to as HybridShapes and are represented by the HybridShape class (Section 8.51).
This chapter describes the creation of 3D wireframe and surface geometry. In addition to the general procedures of creating points, lines, ...
