Hi Chris;

Thanks for the offer.

Since I use PCs, your program wouldn't be possible for me.

What I was interested in would be the 3-D coordinates of the corners of the nodal planes. But it was just a thought, nothing you should go to any effort for unless you had a need for my PC program.

I'm at
