It might be difficult to create an intuitive user interface, but you should be
able to accomplish the pan and zoom actions using sliders or buttons on the
front panel in conjunction with VI Server calls on the diagram.
Wire a 3D Graph reference into a property node and check out the properties
that you can set programmatically. I think you'll want to use ViewDistance
(zoom) plus ViewXCenter and ViewYCenter (pan) to get what you're after. In the
panel button scenario, you might put a "Zoom In" button on t
he panel tied to a
case structure on your diagram that multiplied the current ViewDistance by
slightly more than 1.0.
