Mark,
That's what I figured but I checked the chains out to 6 decimals. Both ending in zeros.
These two chains are just a couple of about thirty sideroads that I used as examples. It's about 50-50 on how they visualize. I will say that all the chains were created using cogo not by graphics.
Esther, send me an e-mail at lhicks@hlcllp.com and I'll be happy to send you any pertenant data for testing.
Thanks
