Lee,
You're right. They do indeed look very good. Surprisingly good, really. And for 30 bucks, how can you go wrong?
I would buy it in a second if there was an easy and quick way to
a) Transfer to and from CAD, or...
b) ...lacking the first point, control contours and elevations with the speed, ease and accuracy necessary to portray realistic representations of our designs. I'd have to look at it a bit closer (we actually have Links 2001 in our office, believe or not!).
Thanks for sharing.
