0.1mm was generating thousands of unnecessary points on straight
edges. Now: 1mm default, 0.5mm minimum, 500 max per edge.
Curves still get proper sampling, straight edges stay lean.
NXOpen Python wraps UF methods with version-specific names.
Now dumps available methods on UF.Modl, UF.Eval, UF.Curve
and tries them in order. Detailed logging shows which method
was found and used, plus raw result format on parse failures.
UF_EVAL.Evaluate() doesn't exist in NXOpen Python.
UF_MODL.AskCurveProps(tag, param) uses normalized 0-1
parameter and returns (point, tangent, normal, binormal,
torsion, radius). Works on all edge types.
