Weird element behaviour.

Discussion created by sercanmetu on May 15, 2012
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();
            ((IZAware)coll2).ZAware = true;

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


            points[4].PutCoords(27, 41);
            points[4].Z = 500000;

            points[5].PutCoords(27.5, 32.5);
            points[5].Z = 500000;

            points[6].PutCoords(40, 32);
            points[6].Z = 500000;

            points[7].PutCoords(35, 39);
            points[7].Z = 500000;

            coll.AddPoint(points[0]);
            coll.AddPoint(points[1]);
            coll.AddPoint(points[2]);

            color.Red = 255;
            color.Green = 0;
            color.Blue = 0;
            //color.Transparency = 20;

            ISimpleFillSymbol simpleFillSymbol = new SimpleFillSymbol();

            element.Geometry = patch as IGeometry;

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.
