I'd be glad to, Bob. I will try to send it to Don via a PM.

Patrick,

If I move to a new vantage point I still get distance and angle to both the top and the tape from the new vantage point. I like using the tape because it's easier to see compared to the base when clutter is present and more accurate than trying to eyeball where the mid-slope is from a distance.

Thanks again for posting these results, great discussion!

Matt
