The real truth is cheapass construction goals. Straight lines and few details are easy enough for less skilled labor to complete and it is easier to hide imperfections when there are fewer details.

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.

Huh? There are zero problems with any curve you can imagine. The issue is that each one is unique instead of mass produced. Most do not spend the $$$ on top.

That house is a nightmare for any craftsman working on it too. You can pretty much forget about most external DIY stuff. Straight lines make for easy projects. Even crooked lines that are supposed to be straight are better than the curves and twists on this thing.
