Weird element behaviour.

Please help.

I created a multipatch geometry and I want to see it on globe control an correct altitude.Although i gave the same coordinates to both feature and element,
element is shown above the feature .Here is my code

element part

IPointCollection coll = new Polygon();
            ((IZAware)coll).ZAware = true;

            IPointCollection coll2 = new Polygon();

            IPoint[] points = new IPoint[8];
            for (int i = 0; i < 8; i++)
            {
                points = new ESRI.ArcGIS.Geometry.Point();
                ((IZAware)points).ZAware = true;
            }

            points[0].PutCoords(27, 41);
            points[0].Z = 100000;

            points[1].PutCoords(27.5, 32.5);
            points[1].Z = 500000;

            points[2].PutCoords(40, 32);
            points[2].Z = 600000;

            points[3].PutCoords(35, 39);
            points[3].Z = 0;

            ISimpleFillSymbol simpleFillSymbol = new SimpleFillSymbol();
            simpleFillSymbol.Color = color;

            IElement element = new MultiPatchElement();
            element.Geometry = patch as IGeometry;

            IElement element2= new MultiPatchElement();
            element2.Geometry = patch2 as IGeometry;

            IFillShapeElement fillShapeElement = element as IFillShapeElement;
            fillShapeElement.Symbol = simpleFillSymbol;

            IFillShapeElement fillShapeElement2 = element2 as IFillShapeElement;
            fillShapeElement2.Symbol = simpleFillSymbol;

            //((IGraphicsContainer)m_globeGraphicsLayer).AddElement(fillShapeElement as IElement, 1);

            ((IGraphicsContainer)m_globeGraphicsLayer).AddElement(fillShapeElement2 as IElement, 0);

why are elemnts drawn the wrong place? What is he way that i can show an element on wanted elevation.
I tried almost everything to correct this situation? Can anyone help me? Thanks in advance.
