Automatically as you create a room in Envisioneer a floor will be inserted. This floor will span from wall to wall of that room and its purpose is to represent finish floor materials in each of the rooms. If you do not want automatic floors, go to Settings-Program Settings-Building Aids and un-check the option. The next drawing you start will no longer include them. Do you want to change the type of floor it is using? It automatically uses the first floor in the Floors catalog. Move your desired floor to the top of the list and it will use it every time. Hope that makes your Envisioneer work, one step easier!
