Summary0032811: Bad result of sweep operation due to Surface Surface Intersect Bug
DescriptionThe first picture attached is sweep algorithm failed。
After analysis, it was found that the SSI [bug_face1_intersect intresect bug_face2_intersect] lost an intersect line[picture 2]
Steps To ReproduceTopoDS_Shape Sh1;
TopoDS_Shape Sh2;
BRep_Builder B;
bool b1 = BRepTools::Read(Sh1, "C:\\sweep_path.brep", B);
bool b2 = BRepTools::Read(Sh2, "C:\\sweep_profile.brep", B);

const TopoDS_Wire & path = TopoDS::Wire(Sh1);//newProfileWires.at(i);
const TopoDS_Wire & profile = TopoDS::Wire(Sh2);//newProfileWires.at(i);
BRepOffsetAPI_MakePipeShell shellMaker(path);
shellMaker.SetTransitionMode(static_cast<BRepBuilderAPI_TransitionMode>(1));
shellMaker.Add(profile, /*WithContact*/false, /*WithCorrection*/true);
const TopoDS_Shape& shape = shellMaker.Shape();

 > lost intersect curve due to no seeds on it . the Param Param Intersect use Deflection = 0.1 to Sample Pnts, which is not precise enough to get all branch seeds
I have change the Deflection = 0.01, which works return 2 curves [see the attached picture PPI_Deflection_0.1.png]. but I known it shoud not change the tolerance to solve the problem

> I have create a branch CR32811 on git and push it.

 Dear @msv, fix is valid, but has test regressions, see
http://jenkins-test-08.nnov.opencascade.com/view/CR32811-master-ifv/view/COMPARE/
and cannot be integrated without fixing bad tests.
Note: branch CR32811_1 was used for testing instead of original branch CR32811.

 The intersection problem is fixed in child issue 0032849, but this case has other problems that must be fixed
The result is valid for " Right Corner" mode, but not valid for "Round Corner" and "Modification" modes for treatment discontinuities.
