I disagree. Most CAD is inherently visual. These code-based systems work great for highly parametric and regular objects like fasteners and gears, or for procedural art, but those are really the tiny minority of CAD tasks. Most of the time you need to see what you're doing and click on stuff.

Most CAD is more similar to graphic design, painting, etc. You wouldn't expect a "code first workflow" for Illustrator, and as far as I know nobody has ever successfully done anything like that.

The closest I've seen are things like UI design tools that can generate code. But a) they usually suck, and b) that is a much simpler problem than CAD.
