Well said. I too visualize quite well. I sometimes struggle a bit with colors but that is easily remedied. At least I have a general idea.

Yeah, I have seldom done shop drawings and yet build things like a portable band saw stand on the fly.

The bird's mouth is deeper on a hip. But it looks like the drape works in your favor there. I'd have to study this more to see what the ramifications are for the ellipse at the rafter edge line. Could make for some interesting cuts on the roof material. The idea of a lath kind of sub roof appeals to me if you shingle it. I think I might go nuts trying to do plywood. Actually I did do that once boxing in the overhang on a Japanese style house. It was what they wanted so you do it. It took way more time than you'd think.

It's been awhile since I laid out a roof or stairs. Probably come back if the need arose. I certainly wish I had been there at the beginning of some layouts I have seen.
