AutoCAD is not written in Lisp. It has been written in several languages, including C. AutoLisp is just a thin scripting layer. See <a href="http://www.fourm

  That 'thin' scripting layer has been used to program some pretty impressive stuff in the engineering and architectural world. Anyway, some more examples then: http://www.cliki.net/Application http://www.cliki.net/Application

There was - probably still is - an application used for designing clothes. The designer creates, I think, a "size 8" and a lisp script generates the other sizes. AutoLisp being lisp-like is really a happy accident. The Autodeskers chose Xlisp IIRC because it was free and embeddable. If they could have embedded a C-like language interpreter, they would have. In fact later, AutoDesk introduced other languages and tried to push users onto them. But AutoLisp already had huge momentum.
