Summary0008169: Wrong Geom2dAPI_InterCurveCurve segment
DescriptionIntersection between the two attached edges' curves ("1.brep" and "2.brep")
gives a segment with first and last points. In these points distance between two
curves is much more than the given tolerance.

 Example of the code:

Standard_Real aP1first, aP1last;
Handle(Geom_Curve) aCurve1 = BRep_Tool::Curve(theEdge1, aP1first, aP1last);
Handle(Geom_Curve) aCurve2 = BRep_Tool::Curve(theEdge2, aP2first, aP2last);
Handle(Geom2d_Curve) aCurve2d1 = GeomProjLib::Curve2d(aCurve1, aP1first,
aP1last, thePlane);
Handle(Geom2d_Curve) aCurve2d2 = GeomProjLib::Curve2d(aCurve2, aP2first,
aP2last, thePlane);

Geom2dAPI_InterCurveCurve anInter(aCurve2d1, aCurve2d2, Precision::Confusion());
IntRes2d_IntersectionSegment aSegment = anInter.Intersector().Segment(1);

gp_Pnt2d aP1 = aCurve2d1->Value(aSegment.FirstPoint().ParamOnFirst());
gp_Pnt2d aP2 = aCurve2d2->Value(aSegment.FirstPoint().ParamOnSecond());
Standard_Real aDist = aP1.Distance(aP2);

Where theEdge1 and theEdge2 are stored in the "1.brep" and "2.brep" files,
thePlane has next parameters:
 axis loc(0; 0; 500) vdir(0; 0; 1)
 vydir(0; 1; 0)
 vxdir(1; 0; 0)

Result distance: aDist = 0.0031472179553542 > Precision::Confusion() !
