And, by the way, the is some bug with roof model. Here is a model made entirely with VA2 / Rhino 6, almost plain VA objects, plus some additional geometry (mostly planes) for controlling objects geometry. The file opened with Rhino 8 / VA 3, without model regenerating looks as it should be:
Some part of them flows above the roof, up to their initial height. And - maybe it is some kind of a clue - there is only a core layer of the walls above the roof.

Hi @jerry.bakowski I didn’t notice that bug when I tested it.
If you change the height of those walls to a smaller value (lower than the roof), the problem seems to resolve.
