Summary0032818: Modeling Algorithms - Result of sweep operation is invalid
DescriptionBRepOffsetAPI_MakePipeShell with the attached path and profile does not build correct on 7.6.0 version.
Steps To Reproduce
TopoDS_Shape Sh1;
TopoDS_Shape Sh2;
BRep_Builder B;
bool b1 = BRepTools::Read(Sh1, "D:\\path.brep", B);
bool b2 = BRepTools::Read(Sh2, "D:\\profile.brep", B);

const TopoDS_Wire& path = TopoDS::Wire(Sh1);
const TopoDS_Wire& profile= TopoDS::Wire(Sh2);
BRepOffsetAPI_MakePipeShell shellMaker(path);
shellMaker.SetTransitionMode(static_cast<BRepBuilderAPI_TransitionMode>(2));
shellMaker.Add(profile, /*WithContact*/false, /*WithCorrection*/true);
shellMaker.Build();
const TopoDS_Shape& shape = shellMaker.Shape();

I think this
         p11 = P1.Distance(BRep_Tool::Pnt(TopExp::FirstVertex(TopoDS::Edge(fit == 1 ? aE1 : aE2))));
         p22 = P2.Distance(BRep_Tool::Pnt(TopExp::LastVertex(TopoDS::Edge(fit == 1 ? aE1 : aE2))));
         p12 = P1.Distance(BRep_Tool::Pnt(TopExp::LastVertex(TopoDS::Edge(fit == 1 ? aE1 : aE2))));
         p21 = P2.Distance(BRep_Tool::Pnt(TopExp::FirstVertex(TopoDS::Edge(fit == 1 ? aE1 : aE2))));

could be simplified a bit by choosing the ref edge first
         TopoDS_Edge aERef = TopoDS::Edge(fit == 1 ? aE1 : aE2);
         p11 = P1.Distance(BRep_Tool::Pnt(TopExp::FirstVertex(aERef)));
         p22 = P2.Distance(BRep_Tool::Pnt(TopExp::LastVertex(aERef)));
         p12 = P1.Distance(BRep_Tool::Pnt(TopExp::LastVertex(aERef)));
         p21 = P2.Distance(BRep_Tool::Pnt(TopExp::FirstVertex(aERef)));


Indentation of the whole new block seems to be incorrect.

Also huge number of differences in images in test results. Please check if the results are compared with the correct version.

No remarks to the code, except probably for the test case - does it make sense to add an image dump?
I wonder, why are there so many differences in images in products? It is unlikely that IFC and OMF are using sweep algo. Wrong refs again?

developer   ~0112164

I think, that image is not needed for this case. Checking shape and number of subshapes is quite enough.
Of course, sweep algo is not used in IFC and OMF tests. Now IFC is in process of changing, ask @smoskvin for details.
For reference I only use branch, which is suggested by jenkins.

Ok, Reviewed then.

Please integrate CR32818 into OCCT.
