HO do i get my stairs to go up the my first floor?

[svalente9GJKH]

Id set my stairs to go to first floor. The result is it sets the riser just short.

my first floor is the subfloor, i need the rise to  go up so that the tread will be flush with the finish floor.

When I try to modify the stair to be first floor +1"  it sets the top of the stair like 6" below.

What is going on here,  do I need to redraw the stairs?

If you want to eliminate the top riser then Edit Stair > Select the Run > Untick End with Riser.

If you want to add a top tread aligning with the floor finish keep then edit the Stair in a plan view, click the Run, drag the Blue Dot at top and drag it toward the floor to add one more step.

I want the top tread to align with my floor finish,  but I don't model my floor 

finish, I want my top of first floor to be plywood,   

 think Revit by default leaves an inch gap at the top of the riser for finish,  but I don't want it to do this.

to remedy this I am trying to make stair top level - first floor + 1" top offset,  but Revit doesn't like this and/or

it DROPS the height of the stair...

is there  a way to disallow that gap?

It should go to whatever elevation you set.  I can show you when I get to the computer.
