This chapter includes all 3D basic shapes or 3D primitives, allowing for the construction of simple 3D models. We presented the
POLYSOLID commands. Also included is
PLANESURF, a command for creating planar surfaces, and two commands for converting existing geometry to solids,
CONVTOSOLID, or surfaces,
In the next chapter, we will see all the general 3D editing commands. The editing commands specific to solids and surfaces are presented in Chapter 7, Editing Solids and Surfaces.
