 To delete one or more spaces
- If the project does not include a space schedule, create one. 
- In the Project Browser, under Schedule/Quantities, double-click the space schedule to open it. 
- Do one of the following: - To delete one space, select the row that contains the space that you want to delete. 
- To delete multiple spaces, drag the cursor across the rows that contain the spaces that you want to delete. The selected rows highlight. 
 
- On the Options Bar, click Delete. You can also right-click and click Delete.  
- At the warning message, click OK. The selected spaces are deleted from the project. The project no longer stores any information about the rooms.  Tip: You can quickly delete multiple unplaced spaces by selecting them in a  space schedule that contains only unplaced spaces.
