How to draw stairs for three stories with dropped landings

[rvbinder]

I'm creating an as-built with HD Pro 2018, Windows 64 bit, running on Windows 10 Pro. 

 

I have the floor plans done for all three floors, and am now trying to add in the stairs. 

 

The attached sketch shows how the stairs in this house use landings one or two steps under the next higher floor. The stairs/stringers are all in the same vertical plane in all three floors.

 

I upgraded to 2018 to try to use the U-shaped stair feature, but I can't get that to generate openings in the floor, lowered ceilings under the landings, and then connect the short part of the U to the higher floor.

 

Please advise.

The stairwell and landing areas should be designated "Open Below" and on their Structure Tabs the "Ceiling above this room" unchecked. Then draw, starting at the bottom floor each stair object and connecting landing and work your way to the top floor. There is NO automatic way to do this, it is all done by you manually per floor.
