I can't seam to find a reason why the roof layout does not enter into the main roof proper. When I change the ceiling height of the extension to 120" the roof does a crazy design causing 4 valley's. The main building has a 96" ceiling height. What am I not seeing here? I've clicked on every button, watched all the videos and read the roof section of the manual and cannot find what to do to fix this. I'm sure it's something simple. Also, I have attached a pic of a structure that I'm trying to design with post and beams elevated above the existing roof. Any helpful hints to layout the roof framing angle at the top of the gable end? Thank you in advance for your time and any help.
