I too am building custom profile walls.
The walls need to vary in width and then I'm trying to add horizontal coursing. I can create the walls but the plan views are distorted. I've heard that if I create too many fills in the profiler, I can slow down modeling, so I've simplified the profiles but still no change in plan. Apparently, that makes no difference.
The model looks fine, plan looks terrible. The highlighted areas are patches to cover the exterior walls. I've created 10 different patches just for the back half of the building and probably need another 10 for the front half.
There must be a better way.
