There is a pipe drawing what is made with routing.
How to set separately linewidth for bodyline(outerline) and routingline(innerline)

RED: Flange, BLUE: Outerline, BLACK: Innerline

I wanna set... RED and BLUE are 'Thick' and BLACK is 'Thin'.

I tried with below code but no result.

public void OuterLine() [COLOR=#EF2929]//Effected not only outerline but also innerline.[/color]
    {
        component cp = targetPart.Tag;
        ufs.Obj.SetLineWidth(cp.Tag, 1);
    }

public void InnerLine() [COLOR=#EF2929]//Not effected.[/color]
    {
        LineSegmentCollection lsCol = workPart.SegmentManager.LineSegments;
        LineSegment ls;

        IEnumerator iEnum3 = lsCol.GetEnumerator();

            iEnum3.Reset();

        while (iEnum3.MoveNext())
            {
                ls = (LineSegment)iEnum3.Current;
                ufs.Obj.SetLineWidth(ls.Tag, 2);
            }

        ArcSegmentCollection asCol = workPart.SegmentManager.ArcSegments;
        ArcSegment ast;

        IEnumerator iEnum4 = asCol.GetEnumerator();

        iEnum4.Reset();

        while (iEnum4.MoveNext())
        {
            ast = (ArcSegment)iEnum4.Current;
            ufs.Obj.SetLineWidth(ast.Tag, 2);
        }
    }
