Hi Andy,
I'll have a look later.
I had been studying a spiral using quarter arcs.

Hi Brian
Having written my last message it occured to me that I could probably work a solution using geometry - see attached .3dm file, which works really well
Take a spiral from your original script and extrude it down to a point, then revolve a curve (to give a lense fisheye effect) and then use curve - intersect for the result
Going back and adjusting the revolved 2D curve gives a real time visual intersection so you can visually adjust to suit your requirements :-)
Best wishes
Andy
