BRepAlgoAPI_Common doesn't work well in a specific case

CommunityOCCT:Modeling Algorithmsnew2 public notes

Description

Hi,

I use BRepAlgoAPI_Common to get the intersection between 2 shapes and the result is an empty shape, but it shouldn't.

I give you the example below.

Tried with v7.9.1

Steps to reproduce

BRepAlgoAPI_Common lBuilder ;
        lBuilder.SetRunParallel(false) ;
        TopTools_ListOfShape lArgs ;
        TopTools_ListOfShape lTools ;
        lArgs.Append(lShape) ; // File Attachment 2 (BREP)
        lBuilder.SetArguments(lArgs) ;
        lTools.Append(lTool) ; // File Attachment 3 (BREP)
        lBuilder.SetTools(lTools) ;

        if (pFuzzyValue > 0.0)
        {
            lBuilder.SetFuzzyValue(pFuzzyValue) ;
        }

        lBuilder.Build() ;

        if (lBuilder.IsDone())
        {
            if (!lBuilder.HasErrors())
            {
                lShape = lBuilder.Shape() ; // File Attachment 1 (BREP)
            }
        }

Hello Commenter 3,
Seems like you did not attach the shapes.
