If you think curves and pillars are hard to represent in software, you’ll be aghast how hard they are to represent with hand drawings.

Your typical architect or engineer of the era would need a kit of dozens of French curves to achieve proper specs in the drawing.

I think auto cad’s role in minimizing residential craftsmanship pales in comparison to pre-fab techniques, fewer craftspeople, high volume assemblies, necessity for faster builds, less old-growth timber availability, and a philosophical shift in the economics of home building that now lean more towards speed and mass production.
