I am working on recreating a shed dormer over a bedroom as pictured here.Attachment 14175Attachment 14176
But I cannot figure out how to properly draw it up. The closest I could do was lower the ceiling 30 inches, add it on in a 3rd floor, section off the dormer with invisible walls, and change the pitch over the window.Attachment 14177Attachment 14178Attachment 14179
When I try to follow the directions for a manual shed dormer, the ceiling that I want to be sloped ends up flat instead.
