Hey! Keep in mind I didn't set-up these drawings I am working on a file that was given to me. The original house had an attic with unused space, and the previous person drew walls on the attic layer. As we all know, this means that no rooms are defined, etc. I'm now trying to get the room sizes, room names to show up on the schedules, etc and for obvious reasons this won't work. Is there a way for me to change this attic layer to an actual floor layer without messing up the roof above?
