FamilyInstance can't be rotated precisely


I am trying to place a FamilyInstance (a curb in this example) at a ModelCurve. The Model Curve represents an alignment. The script works but somehow I get a slight offset at the end of the curb which I can’t explain for myself. If I check the vectors, endpoint and rotation angle it shouldn’t be there. Is somebody able to help me?

Can sent the script also including the costumnode?
