If I define a Window with Wallhole2 command to get some extra parts for the window,
this wallhole commands causes that the default wallhole-cut will be inactive.
IF I now write: IF fasche THEN WALLHOLE2
Then the default wallhole-cut will be inactive as well, if fasche=0.
The default wallhole-cut is smart and I want to use it in the case fasche = 0
and I do not want to write an extra wallhole command for that case.
