I am a very new user here, working on my first plan in CA after years of working in Sketchup. CA seems great but there is a lot of information to take in.

I have drawn a floor plan of a house but the walls are not healing around the floor system in the 3D rendering. I quickly drew another shell with the same set of defaults and the walls were continuous, so the issue is not a hardware problem, rather something I have done to the model settings to create this problem!
In the 2nd Floor default settings I have selected "floor under this room", and given the floor structure all of it's layers.
I am sure the problem is an obvious one to someone, just not to me!
