Hi, I have this block and one rectangle on top of it. I need to deleted the “window” face in the rectangle. I have seen couple of videos but nothing works for me. I can select the top face of the block and delete it but there never will be the hole in the big gray rectangle. It behaves like it is two different object. I can draw small rectangle into the gray one. If I delete it it will not keep hole. I can delete the face of the inner rectangle but the man face still stays unchanged. How to fix this?
I will send the skp
