Oh, never mind. You said, "In iTools." I've got to go take a nap.
I didn't finish that story until 3:30 AM last night, then
I was too wound up to go to bed. I'm not even reading the
posts right now. Sorry.
Cheers,
David

You could have a look at FSC_SURFACE to see how this is done.
It maintains the aspect ratio of the X and Y data. It is
straightforward to apply this to the Z direction, I think.
IDL> FSC_Surface, dist(30, 10)
