I'm modeling a complex stair which has a continuous wood outer guardrail and a glass inner guardrail. The stair is a partial spiral stair in plan. I currently am having two issues in regards to modeling the guardrail and the handrail.

1. Guardrail is being modeled as a glass curtain wall. For each run there are 3 walls, 2 straight and 1 radiused. Where the straight run meets the radius is not a perfect tangent. The glass guardrail is intended to extend past the stair stringer and I want to add an angled panel break to allow for translucent glass below the stringer line and clear glass above. On the straight runs I'm able to alter the curtain grid and rotate to the desired angle but because the curved curtain wall is hosted top and bottom to an angled reference plane, I'm not able to rotate the curtain grid, only change it's X,Y coordinates. Any idea on how I can create an angled curtain wall grid on a curved wall?

2. As you can see in the screenshot below, my handrail is doing a funny kink where the radiused and straight components of the stair connect. I think it's kinking because the point where the straight line intersects the radius is not tangential, so does anyone know how to make Revit ignore this condition and just make the rail run and a continuous angle?


Thanks!
