This is the eighth edition of the popular AutoCAD reference-tutorial, the AutoCAD and AutoCAD LT Bible, by Ellen Finkelstein. Because of its comprehensive coverage, it is very popular among both novice and experienced users. Even some of the employees at Autodesk keep this book at their workstations. Coverage of AutoCAD LT--an inexpensive, 'light' version of AutoCAD--is also incorporated throughout the book. The book begins with a Quick Start tutorial, so that even beginners will be doing exciting work with AutoCAD on their very first day. The chapters begin with the basics of creating drawings, using commands, and specifying coordinates. Finkelstein builds on this these chapters to cover more complex 2D and 3D drawing techniques, including using layers, creating dimensions, 3D coordinates, solids, and rendering. Finally, the book discusses advanced topics such as customization of commands and toolbars, and programming AutoCAD using AutoLISP and VBA. A CD-ROM contains before and after drawings for each tutorial. All of these real-world drawings have been collected from AutoCAD professionals.
