The space schedule lists all spaces defined in the building model. For any spaces that are currently unplaced, the schedule displays Not Placed for any read-only fields, including Area, Perimeter, Level, Upper Limit, and Volume.
This filters the schedule so that it lists only the spaces that are unplaced or not fully bounded (enclosed). You may want to save this schedule so that you can quickly determine which spaces need to be placed or fully bounded (enclosed).
To redisplay all spaces in the schedule, for Not placed/enclosed, select Show.
