Hi, I'm new to CA and having a hard time with a 4 way gambrel roof. The design is basically a plus sign, with all 4 sides being a gambrel roof, 16:12 and 7:12 lower and upper pitches respectively. I can get two sides of it, but the other two don't seem to want to cooperate. The front walls on each side are gables, while the sides of each side are hips with 2nd pitch added. I tried adding invisible interior walls that run half way into the structure from each side of the roof for hip support, but no luck. Any advice would be appreciated! Thanks. Image attached.
