AutoLisp is a dialect of
LISP; a small subset of the
Common Lisp programming language. It has extensions that support the manipulation of graphical entities. The properties of these graphical entities are stored as [association list]
?s in which
AutoLisp "group codes" are paired with values that indicate properties such as points, radii, colors, layers, linetyptes, etc.
AutoLisp is included with the CAD
? program Autocad
?. It is not included with the "
AutoCAD LT" product line.
