Cut Paneling

Hello everyone! I have been trying for some time to do paneling of a facade. I created two surfaces, one with cuts and the other with panels and then I wanted to join the two but the paneling, then, does not follow the oblique lines. By following some tutorials I can only get the panel to be rectangular but not “trimmed”. I’m trying various commands like trim etc. but I can’t figure out what to do. I will also share with you the code that maybe it is easier to understand what I have done
Thank you very much! (43.5 KB)
