Thanks Dan, I still don't understand the logic completely. I would think that the room definition would control such things not the wall types.

That's a good point. It does seem logical that room def should control the hole in the terrain.

One other note here is that you can always create a terrain hole from a polyline, if needed, and uncheck the option in terrain to hide terrain intersected by building. Then you have ultimate control.
