I was being facetious about the literal use of a computer
CAD software is meant for precise dimentioned designs made from extruded 2D sketches
This exactly what I'm arguing against. Parametric CAD like Solidworks and whatever you'd call AutoCAD don't get to own the term.
What I was trying to say, and was not very clear, is that CAD is an umbrella term for a wide variety of programs that generate digital models for use elsewhere, whether that's manufacturing or animation. There are different subdomains, like surface modeling (blender) and parametric modeling (solidworks), but no single subgroup is necessarily the 'true' CAD. They're all computer-assisted design programs, just specialized with different approaches for different purposes.
