David, thanks for the response. I had surmised this was the issue but it was difficult to tell for certain.

I'm new to HD Architectural 2018 and am a previous user of a 2009 version of CA. 

I'm trying to create a roof like in the attached image. This means the adjacent exterior walls have differing heights (I'm pretty sure I cannot simply define different heights to walls in the same room). The shallow pitch side of the roof is 3.5/12 and the deep pitch is 10/12. The auto-generated roof creates a large 3ft + overhang instead of treating it like the image. The online videos show that I may be able to modify the height of a roof plane but I'm gathering I can't do it with Architectural 2018.

Any tips would be greatly appreciated.
