It was designed to help users automate repetitive tasks and create custom commands by interacting with AutoCAD’s drawing database. AutoLISP, introduced in the mid-1980s, is a dialect

AutoLISP and Visual LISP represent the evolution of automation within AutoCAD, transitioning from a basic list-processing language to a sophisticated extension capable of direct object manipulation. While often used interchangeably, of "vanilla" AutoLISP, introducing a dedicated Integrated Development Environment (IDE) and access to the AutoCAD Object Model via COM/ActiveX.
