Summary

0024145: OCCT fails to project a wire onto BSplineSurface using BRepAlgo_NormalProjection

Description

When projecting the first attached wire, the BRepAlgo_NormalProjection throws an exception:

restore face.brep f
restore wire1.brep w1
#throws a Standard_ConstructionError:
nproject r w1 f

When projecting the second attached wire, there is not any exception, but the result is still not built:

restore face.brep f
restore wire2.brep w2
nproject r w2 f

Finally, when projecting the third wire, everything is OK:

restore face.brep f
restore wire3.brep w3
nproject r w3 f

All the wires lie on the face and are essentially the same, only translated a little. I have also attached a simple c++ code that was used to generate the face and the wires.

Steps To Reproduce

See description above.
