If you have unnecessary balloons, select ‘Delete QA symbol’ from QA menu and click the unnecessary balloons to delete. If you need to correct deleted balloon number(s) in the balloon number sequence, select ‘Renumber’ from QA menu. Then the balloon number sequence will be corrected (example [1,2,4,5,7,8,10] --> [1,2,3,4,5,6,7]). Also you can easily change a balloon's number. You just need to double click a balloon, then the balloon's Add/edit QA attributes symbol window opens. You type a new balloon number and press the OK button.

You can also undo last auto-ballooned result with pressing [Ctrl] and [Z] keys together, but only if done straight after the operation, and there is currently no redo function in the QA-CAD software.
