The "design space" of architectural CAD models is mostly illegal (e.g. does your AI know how many parking spaces you must provide?) and/or lethally dangerous (e.g. is that beam strong enough?) so in the real world a constraint solver that saves time by automatically drafting, according to detailed specifications, detailed plans that certified architects and engineers can then analyze and sign off is the most useful possible tool.
