Hi once again.  
I have an object that ‘floats’ around a scene and when do mouseClick on it I need the Vector3D(x,y.z) instead of Object3D. \_mouseVector is Vector3D var  
Can anyone help with this please?  
Regards  
FJW  
\<code\>  
private function onMouse3DDown(ev:MouseEvent3D):void  
{  
var obj:object3D = ev.object; //this is ok  
\_mouseVector = new Vector3D(ev.scenePosition.x, ev.scenePosition.y, ev.scenePosition.z); //this fails with access of invalid property scenePosition  
trace(\_mouseVector);  
}
