`GeomFill_CorrectedFrenet` hangs in some cases

3

### Description `GeomFill_CorrectedFrenet` law is not usable on some curves because its initialization never terminates. ### Expected Behavior `law.SetCurve(curve)` terminates properly and we can proceed to use the object. ###...

For some STEP files we fail for geometric tolerances to read the "geometric_tolerance.magnitude"

2

### Description For some STEP files we fail for geometric tolerances to read the "geometric_tolerance.magnitude" as a StepBasic_MeasureWithUnit. The parameter 3 may be of type StepRepr_ReprItemAndLengthMeasureWithUnitAndQRI or StepRepr_ReprItemAndPlaneAngleMeasureWithUnitAndQRI. There is...
