Congratulations, you found a very nice way to use the doorOrWindowCutOutShape# property! [:)
Thanks, but yours is the implementation of the cut-out. I just tested it

. Slightly modified the models above, when I realised the real window looked a bit different (walls not visible around the window ledge).


Note that making it more elaborate is not difficult, but the point is making a generic, simple model that gives the general impression of the façade with the illusion of an old-style window. And, of course, to test the cut-out of 4.2.beta.
ok
