Extruded and Planar Surfaces

Surface models are a step up in realism from wireframe models because their surfaces can hide objects, and they can assume material properties and reflect light in renderings. Your exploration of surfaces begins in this chapter as you concentrate on wireframe objects that have surface-like propeties, and on the AutoCAD commands that make flat surfaces. Even though these commands are limited in the shapes they can make, they are extremely important commands because so many objects and surfaces in the real world are flat.
