If a room schedule includes unplaced rooms, you can omit them from the schedule.
The room schedule lists all rooms defined in the building model. For any rooms that are currently unplaced, the schedule displays Not Placed for any read-only fields, including: Area, Perimeter, Level, Upper Limit, and Volume.
This tool filters the schedule so that it lists only the rooms that are currently placed (and enclosed).
To redisplay the rooms that are not placed or enclosed in the schedule, click (Show).
