I think you can not mix index based geometry with non-index based geometry within one geometry (I might be wrong here! ). If you want to draw a line outside the pyramid, then attach another geometry to the geode doing just the line in a way you want. Are yo after drawing an arrow? If so, your approach will rebuild the arrow geometry for each matrix transform - change. -Nick
