BRepAlgoAPI_Common gives bad result

CommunityOCCT:Modeling Algorithmsresolved2 public notes

Description

Hello,

The whole Attachment 1 (BREP) (see attached files) is considered as common part between Attachment 1 (BREP) and Attachment 7 (BREP) but that's clearly wrong (see attached picture)

Steps to reproduce

BRepAlgoAPI_Common lBuilder ;
        lBuilder.SetRunParallel(false) ;
        TopTools_ListOfShape lArgs ;
        TopTools_ListOfShape lTools ;
        TopoDS_Shape arg, tool ;
        BRep_Builder builder ;

        BRepTools::Read(arg, "Attachment 1 (BREP)", builder) ;

        lArgs.Append(arg) ;
        lBuilder.SetArguments(lArgs) ;

        BRepTools::Read(tool, "Attachment 7 (BREP)", builder) ;

        lTools.Append(tool) ;
        lBuilder.SetTools(lTools) ;

        pFuzzyValue = 1.0e-6 ;
        lBuilder.SetFuzzyValue(pFuzzyValue) ;

        // Proceed !
        lBuilder.Build() ;

        if (lBuilder.IsDone())
        {
            // No errors ?
            if (!lBuilder.HasErrors())
            {
                // Extract shape
                lShape = lBuilder.Shape() ;
                BRepTools::Write(lShape, "Attachment 2 (BREP)") ;
            }
        }
