Thank you! that worked!
I Also found one thing to improve:
instead of deleting the hole line with "sash" I just changed the endAngle from "-1,5707964" to "-0,01" for all Windows.
I did that with the search and replace command of the editor. Now I can open/close Doors with "replace" in seconds, because all Doors still have -1,5707964 in and all windows -0,01.

Thank you for your help!
