I don't know if this qualifies for tricky: if you recall that everything is an expression, and since version 6 this is true also for displayed graphics, then it is just the most natural thing to do... Put this in front of the displayed Graphics3D and evaluate the resulting expression: AbsoluteOptions@ hth, albert
