When you add an area to a floor plan, the project stores information about the area. This can include information that you add using area properties, such as the area name, usage, and so on. See About Area Properties.
You can see information about areas in an area schedule. If you want to retain information about an area but remove it from its current location in the building model, unplace the area as follows.
To unplace an area
Check the status bar to be sure that you are selecting the area and not the area tag.
The area is removed from its location in the building model. However, the project still contains the information about the area. In an area schedule, the area is listed as Not Placed. If desired, you can place the area in another location. See Placing an Unplaced Area.
