my father was a draftsman and so I grew up with blueprints and a drafting table in the home. He was also a user of the earliest CAD systems, including AutoCAD (by a vendor named Autodesk). It had a Lisp-like language built-in named AutoLISP. It was the first Lisp running in my home that I can remember or at least the first I interacted with.

CAD systems were clearly meant as a software tool for the kind of workflow previously done by hand, by draftsmen, involving printed blueprints. And a Lisp was exposed for user interaction about as early as you can get. When I interacted with it myself it felt like I was dealing with a REPL exposed by a Lisp VM (ported to an IBM PC class machine in the MS-DOS era) that also happened to have a graphics renderer and screen display. And I note the OP's college student "thesis" paper alone was written over 30 years after AutoCAD shipped to my family's home.

So I am not clear if the OP is just ignorant of CAD's history, or they are making an intentionally baiting and misleading claim.
