Summary

0028926: Extrema between circle and NURBS surface give wrong result

Description

The extrema between the supplied circle and surface give an incorrect result. The closest point found on the circle is located on the side of the circle, which is visually farter than the possible real solution (see attached picture)

In DRAW:

Draw[1]> pload ALL
Draw[2]> vclear
Draw[2]> vinit View1
Draw[2]> restore c:/temp/extrema_bug_circle.brep c
Draw[3]> restore c:/temp/extrema_bug_face.brep f
Draw[4]> distmini r c f
Draw[5]> vdisplay r
