I'm sorry y'all. My question was pretty vague. I'm going to be converting an existing barn into a living space. The roof is a barn style which has 2 different pitches on both sides. It also will have a partially vaulted living room with a 3' tall dormer that will be flush with an exterior wall. I'm having trouble with creating those two things. I hope that explains it better. I tried uploading a couple pictures but they're too big.
