Open Tall Room Not Sitting On Walls

[AlexAncon]

The upper portion of the Gallery (long tall hall) is supposed to sit upon the lower walls and be wider above than below. I have the upper portion defined as "Open Below" but it is then cutting off the ceiling joists of the adjacent areas.

 

How would you adjust to make this work?  I thought about putting a polyline "hole in floor" but that seems tricky to cut tight and yet not slide the edge off the sheetrock below.  I also wanted to be sure that the upper area wasn't included in the square footage calculations of living area.

 

It should look more like the black and white line drawing rather than the colored one.

 

 

Thoughts?

Place invisible walls that line up with the walls below and that space can then be "Open Below" the other two slivers defined by the invisible walls and visible walls will merely be second floor space.

Use Room Dividers to create the Open Below area. This introduces some other issues, but it will create your section correctly.

Thanks gentlemen!  That told me what I needed.  I appreciate it!
