Huanle5062, very kind of you.
It is all in the P.Y value of the Linear field. As I mentioned above, I changed that just a little bit, allowing the windows to fly into the final frame, but only a little bit. This was my sweet-spot between how it looks and how I have turned windows into a building to get them into the final position (I designed and built in the city of Berlin buildings over ten stories high, and I drew from that experience). Anyway, not important, you want to have them fly in and be flat with no corner peeking inside of the structure at all. The P.Y value of the Linear Field has been adjusted accordingly. Please have a look.

I go ahead and assume that if flat montage all the way is wanted, then the intersection is not desired as well. If so, the Inheritance Effector solution is the way to go, which the initial source just being a copy (scaled) of the “building-polygon”. Now, no windows intersect, and no windows fly into the structure.
I have screen-captured with one frame per second what I see here, no intersection, and no flying into the building.

Thank you Dr. Sassi! I will have a look later. It would take a while because I’m having a project to work on now.
