Solver, I thing I got it figured out. I was building the main walls for the house. Building the foundation. Then trying to add the exterior walls for the porch. Was giving me issues. But I just tried again. I added all the walls including the porch. Built the foundation then added the strait foundation walls directly under the inside exterior walls of the porch. It worked.
