Summary0023314: Helix curve distortion
DescriptionLoad attached brep file. Try to build a helix along a period surface using API
Handle(Geom2d_TrimmedCurve) aSegment = GCE2d_MakeSegment(startPnt , endPnt);
edge = BRepBuilderAPI_MakeEdge(aSegment , hSurf);
BRepLib::BuildCurves3d(edge);

The startPnt is (0.0,0.0), endPnt is (PI2*22, 51.024) (means 22 rounds), the hSurf is the b-spline surface in the file.
When round is 22, the helix curve is distortion, if we decrease the round to 10, the curve is correct.

Thanks.
