Wall Joining Gone Wrong

[Really 0]

Please see attached to better explain the problem.

 

Please provide a layer or Wall type to make this work correctly.

 

The Beam is to move to or over the horizontal wall as shown for the raised entry.

The little wall disappears and the angled wall merges with Pony wall.

 

Maybe I'm missing a button or small tip, that will fix this.

 

Thank you all that help!

If I understand what you want correctly, you can use attic walls for that, or you can make that a room with a low ceiling height/ roof height. I assume those are invisible walls below. You may need to turn off auto attic walls and create your own manually, to get them to stick.
