0025967: Shape Healing fails to correct a face with missing poles and pcurves
SH fails to fix a particular case of a sphere-like closed surface of revolution with only two 3D curves (corresponding to seam-edge).
Apparently FixShifted and FixDegenerated fail to create a closed 2D contour.

The model originally comes from an IGES file.
restore face-no-sh-fwd.brep
fixshape r f
numshape r #must be 4 edges, instead there are only two
pcurve r
2dfit #zero area contour is displayed instead of natural boundary
No tags attached.
