Stairs problem

[cadpro78]

I'm trying to figure out how to make this stair with a landing work in Revit. Any suggestions?

Could it be the boundary line at the top, which is too long ? Besides that the sketch seems to be OK... :beer:

Thanks for info. That seem to have been the problem. A few extra lengthy lines.

I get that error if a boundary line intersects with a riser line as well.....moving a boundary split an inch or two away from a riser helps
