Introduction

In addition to the primary methods involved in 3D solid modeling, AutoCAD has numerous other commands and techniques that facilitate the creation of particular 3D shapes. These include commands that produce regular 3D solid primitives, such as cones and spheres, commands that allow you to create 3D objects by revolving or extruding 2D outlines of 3D objects, and commands that create mesh models that can be shaped in ways ...
