0023386: BRepAlgoAPI_Fuse on two disjoint shapes sometimes loses all geometry from one of the shapes
Sometimes BRepAlgoAPI_Fuse will correctly return a compound of two disjoint shapes that are input. The attached file contains two .brep files that when sent to BRepAlgoAPI_Fuse results in geometry equal to only the b.brep.
BRep_Builder builder;
TopoDS_Shape a, b;
BRepTools::Read(a, std::ifstream("a.brep", builder);
BRepTools::Read(b, std::ifstream("b.brep", builder);
TopoDS_Shape c = BRepAlgoAPI_Fuse(a, b);
// c does not have any geometry from a.

No tags attached.
