contour has no visible color and thickness?

When i create a contour with this code. I see the contour only in wireframe mode. 
What i do it wrong?
Iwould like to have a red thin outline. And also would like break appart this outline.

        {
            corelApp.ActiveDocument.Unit = cdrUnit.cdrMillimeter;
            corelApp.ActiveSelection.Shapes.All().Group();
            corelApp.ActiveLayer.Shapes[1].CreateContour(cdrContourDirection.cdrContourOutside, 3.5, 1, 0, corelApp.CreateRGBColor(255, 0, 0), 
corelApp.CreateRGBColor(255, 255, 255), corelApp.CreateCMYKColor(0, 0, 0, 100), 0, 0,cdrContourEndCapType.cdrContourRoundCap, cdrContourCornerType.cdrContourCornerRound, 15); }
