This document provides an introduction to 3D modeling in AutoCAD. It discusses the need for 3D, including making projects more realistic, easy to understand visually, and better for marketing. It also notes benefits like easier remodeling and fewer language barriers. The document outlines different 3D model types like wireframe, surface, and solid models. It describes how to use basic 3D primitives like boxes, cylinders, spheres, cones, pyramids, toruses, and wedges to build solid models. Finally, it wishes the reader the best with AutoCAD 3D.
