Precast Concrete Stairs or Steps?

[m_cahoon14336]

I have been working with the stair tool with little success. I am trying to create an 8' wide concrete stair with (5) 7" risers and 11" treads. The bottom of the stair needs to be open. I know I could make this as an extrusion, but I would like to make it with the stair tool if this is possible. Could someone "stair" me in the right direction with this.

I'm not sure I understand when you say the bottom of the stairs need to be open. Have you seen the stair samples file from the Revit Web Library?
