Davidjames - autobuild does work, but manual does not. I do start with the outside wall.
Jon - In my simple drawing, the default ceiling height in the floor was set to 8'. When I changed it, the build worked correctly.
My problem is that the house will have different roof heights. A family/ great room with 12', the rest is 10', and a couple of storage areas that will drop to 8'
Drawzilla, I want the walls to be higher-- that is the problem, the roof was going to low.
I thought that if I change the ceiling height in each room that would be sufficient, however that does not seem to be the case. Another way I found was to choose the open/transform box and change the z factor, but it seems like some setting is overriding my work.
