PolyCurver Door

Hello everybody
I have a problem want to ask. How to get the curve of the opening the wall, or when the door inserts into the wall as same in picture.

I have the exact same issue I’m struggling with now, anyone? :frowning:

This is quite a complicated task because you can’t get opening cut as an element itself. Thus in this method you need to select the wall and the door.
