lost rooms?

[tomagardner]

Hi Folks! Love the program. Stairs are a little tricky. Wish I could lock them when they are right.

But now I seem to have lost "rooms" on my first floor and some in the basement. My walls are all connected, but I can't "select" them as "rooms". In my 3D view they look like there is no floor.

TIA, Tom

Thanks anyway, one of the walls was designated "no room definition."
