Hello all,  
	I am trying to recreate a real house in Home Designer Pro. The existing project has a complex outer wall design, where most of the wall is 30cm thick brickwork (with plaster on both sides), but there are 2 alcoves on each side of the building which are much thinner (~10cm) and built out of wood. I can model them fine for the most part with different wall types, but I run into problems when there's a corner of the thicker wall that only has 10cm of the ticker wall in use.
 
	 
	As soon as I connect the interior wall to the exterior one, HD forces my thick exterior wall to be shorter, and expands the thin one.  
	How do I prevent this from happening?
