On one of my plans I seem to have accidentally deleted the wrong area in a couple of places and now the rooms don’t have floors. I recall in the previous version of floorplanner there was a keyboard command (ctrl-something?) that would make the areas go back to what they should be based just on the current positions of the walls. But I can’t remember what the command was, or if it’s still in the new version. Is there another way to fix the floors without deleting a whole bunch of walls?
