I am new in Blender. I have basically done mesh walls, and I want to cut away doors.
So I select each wall, take boolean "difference" and select the red rectable (that should represent a door)..
But something weird happens. I can see the wall has been slightly changed at the door, but no cut out.
What I am missing?

I have also done a video
I can upload the Blender project if needed.
