Creating Surface Models

In this chapter you will create a conceptual model of the O2 Arena in London, the same model used in Chapter 16, “Navigating 3D Models.”

In AutoCAD, surfaces are defined as infinitely thin shells that do not contain any mass or volume. Two-dimensional profile shapes have been provided in the chapter's sample file that you will use to create 3D surfaces. You will begin the following exercise by creating a planar surface, and then revolving, sweeping, and extruding 2D profiles into 3D surfaces.

Making Planar Surfaces

Planar surfaces differ from flat bounded areas like circles and closed polylines in that they display surfaces rather than edges only, in shaded visual styles. In the following steps, you will create this simplest ...
