Early in the project I had deleted the 2nd Floor level in Elevation thinking I wouldn't have a need for multiple floors. Well, the client has decided to put ina 2nd Floor. So now I still have a 2nd floor referenced but I cannot show a 2nd Floor symbol in elevation or section. When i try to place/rename a symbol as 2nd floor @ 12'-0" it says the level already exists. Is there any way to replace a level tag after deleting it?
