Auto/Visual lisp help. AutoLISP | AfraLISP. What can AutoLISP do? AutoLISP can be used simply to automate repetitive tasks or to build complex programs that extend AutoCAD and make it more productive. For example, you could write a program that calculates the total length of polylines on a particular layer - imagine how much time that would save over doing it manually! What's so good about AutoLISP? The great thing about AutoLISP is that it's pretty easy to use - even if you haven't done any programming before. A complete beginner can easily create a simple routine that could save hours or days of work, making AutoCAD much more efficient and the drawing process much less tedious. People may tell you that AutoLISP is too limited and not powerful enough and that the higher-end languages are the way to go with AutoCAD customization.
