Summary0023998: Bad result of intersection of two faces: curve has a loop
DescriptionTwo faces received from customer OpenMind are intersected with a loop caused by wrong set of 2d points on the closed BSpline surface: the first point of open-ended 2d-curve is added once again at the end of the curve.

Additional information
and documentation updates		Modified entity:

IntWalk_PWalking

modified method:

Standard_Boolean IntWalk_PWalking::TestArret(const Standard_Boolean DejaReparti,
TColStd_Array1OfReal& Param,
IntImp_ConstIsoparametric& ChoixIso)

The problem was in unfounded addition of first point of open-ended 2d-curve to the end of the curve. This operation is done after check of the flag <close>. This flag was set to TRUE after check of closedness of 2d-curve on surface S1 and closedness of 3d-curve. But in fact, all curves (2d and 3d) are closed only if two 2d-curves are closed (on S1 and on S2). So this modification has been done in method TestArret.
