Here's a screenshot of my latest problem. I have an attached garage - via a small open porch - with a truss roof, all four walls are set to 8'. The top of the porch wall lines up with the top of the garage walls. When I try to Fit Wall to Roof on the gable ends, they shoot up through the roof. Also notice that the end dimensions are not 8', in fact they're two different dimensions. I can get the siding to Fit to Soffit, but the drywall still pokes through. This is a custom defined wall, so I set the drywall to Fixed (8') to no avail. The wall definition isn't really complex, I just changed the siding and drywall definition from a standard 2x4 exterior wall.
By the way, how do I put a 24" round window up at the top of the gable, assuming I can get this first problem fixed.
Thanks for being there!
