Yorik,
it would be nice if you can fix it.... if I could give you this missing time..... maybe just something to change regarding window design or behavior when fusioned with the wall (for rotation only, since it seems to work well for translations)
and a small question: is it possible that in preset windows, the frame does not inherits transparency or have it's own transparency ?
In my house design, I move or rotate all parts by base elements, and this works perfectly, only windows do not behave smartly....
I attach the design. the group 'parts_for_move' is there for moving the whole house, 'parts_for_rotate' for rotation, it would be nice if this group could be removed and just use the first one.

thanks for the link. I'll try to understand this.
