Good evening, I have a problem with the '' Floor Opening '' command in the '' Create Room '' panel, it hasn't pierced the floor for a few days, but only the perimeter of the rectangle on the floor itself remains visible. I need to use it because I have to make top view views of a first floor that the staircase reaches from the floor below, I could use the '' edit floor 'command but the rectangular hole is much faster. Thanks to those who will be able to answer me.Emanuela
