You can use PickZoom  behavior and attach it to your SceneGraph.      2. You could use PickObject class to pick your object and create a PickingCallback           method which can zoom your transformgroup. Add the PickingCallback method           as the callback to your PickObject behavior.

But I don't want the mouse zoom feature. I wish to do zoom window by selecting a portion of the scene graph and scaling them. Got any idea on this?

But the arc, text etc are not   zoomed but only translated.. Can anyone tell me whether what I did is correct or   not? If yes, why it is not zooming all the objects? Is my approach correct?   Regards,   ishwari
