Essential AutoLISP®

AutoCAD is one of the most widely used computer-aided design packages. This handbook is an introduction to the computing language of AutoCAD, AutoLISP, as well as its applications. Part One contains an easy-to-learn pictorial representation for data and code, a tool used to easily solve problems otherwise approached through trial and error method. The second part is devoted to learning how AutoLISP processes the code entered. The work not only explains the causes of most common error messages and how to solve them, but examines many other errors that do not necessarily give messages.
