Why it can’t make a floor and force me to delet it?

Revit is awfully picky about the type of Nurbs Curves it accepts.

Still can’t make the floor after changing nurbs curve degree to 3 of more.

Try to draw a spline floor through the revit ui with a single closed curve. This is something that revit simply does not support…


Oh yeah, Dimitar is totally right. That piece of documentation in Revit API forgets to mention that closed Nurbs Curves are not acceptable either. You will need to cheat the system and basically split this into two open curves or inject it with yet, another type of curve like a small line segment. Revit SUCKS!
