Restores erased objects. 
Summary
 
   
   
	 OOPS restores objects erased by the last 
	 ERASE command. 
  
 
  
 
  You can also use OOPS after 
	 BLOCK or 
	 WBLOCK because these commands can erase the selected objects after creating a block. 
  
 
  You cannot use OOPS to restore objects on a layer that has been removed with the 
	 PURGE command.
