Question:
Why are curved polybeam rods not intersecting correctly with parapet posts, but have a small offset?

Answer:
The rods are quite long (nearly 100m) and the polybeam points were picked on the parapet posts so that the shape was a curve. Adjusting  XS_POLYBEAM_CURVATURE_TOLERANCE might help. In this case the value was changed from 2.0e-6 to 2.0e-10.
