AutoLISP is a high-level programming language used within AutoCAD. It enables users to customise their installation of AutoCAD and to carry out repetitive design tasks quickly and efficiently. A Practical Guide to AutoCAD AutoLISP introduces all the main AutoLISP functions and commands and takes the user through a logical sequence of study suitable for college-based courses or for distance learning. It assumes a basic knowledge of AutoCAD and covers all releases up to Release 14. Each part includes practical examples based on real-life industrial problems, and exercises which encourage the reader to test their knowledge and apply it to their own specific problems.
