Entering as-built rooms
As-built rooms are entered in the as-built layout (separate drawing files saved previously). You can use the
Room and
Auto-Room tools to create rooms.
Note: If you want to use the
Auto-Room tool to create rooms, it is important that as-built walls and new building walls are in different drawing files and that you activate the Intersect option after having selected
Auto-Room. This applies regardless of whether you want to create as-built rooms or new building rooms.
