Revit 2014 - Component stair - If you don't end with riser the last tread is shorter?
I created a normal Assembled stair, nose 2cm, riser thickness 2cm, tread 2cm.
Minimum tread depth 28 cm.
Create the stair.... run can be any length. Now select it, toggle end with riser on and off, and see how the last tread has a length of 26 cm ( +2cm nose ) instead of the normal 28 cm ( +2cm nose)
