Even after all these years, I still have a lot of problems with roofs. This time I'm trying to match the height of a wall to the underside of a roof. I'm attaching a screenshot of what happens. One side of the wall matches perfectly, but (maybe) because I choose one of the roof slopes as the upper height, the part of the wall under the other slope extends above it. I'd just divide the wall into two walls, one under each slope of the roof, but then I can't put a window in the center of the wall.
Any advice/help is appreciated!
