"AutoCAD 2021 3D Modeling focuses on the 3D aspects of AutoCAD 2021, providing both new and professional users with step-by-step procedures for creating 3D models and working with AutoCAD's many features. It presents these techniques in both metric and imperial units, like the preceding book, making it useful for a worldwide audience as it surveys the program's many design tools. A companion disk of drawing exercises and projects compliments discussions (also like the prior book) and expands the workshop feel of the instructions."
