it seems that this Projection-Algorithm of the class GeomAPI_ProjectPointOnSurf is not working precise enough.
Ich project all poles of a BSPlineCurve onto a cylindrical surface. At first glance, the projected curves seem to be quite okay.
If I zoom the projected points, it is visible, that they never lie excactly on the surface.
I looked at the sourcecode of this OCC-class and found no hint about how to force a greater precision.
Did anyone of you experience comparable results ?
