Is this line giving you the correct 2d coordinates when you drop an
object:?
view3D.findHit(view3D.session , view3D.mouseX , view3D.mouseY);
Have you tried doing something like this? (untested)
private function _onDragDrop(e:DragEvent):void {
view3D.findHit(view3D.session , view3D.mouseX ,
view3D.mouseY);
view3D.fireMouseEvent(MouseEvent3D.MOUSE_UP, view3D.mouseX,
view3D.mouseY);
var evt:MouseEvent3D =
view3D.getMouseEvent(MouseEvent3D.MOUSE_UP);
// the rest of your code
}
