Thanks Andy. My apologies for forgetting who you were, and for taking so long to locate the programme. As your original message was on the ME Clearing House, it is little wonder that I had no email about it. I will send it off-list. For everyone else, calculating the elevation on curves can be time consuming. After discussing it with Marv Klotz (see: http://www.myvirtualnetwork.com/mklotz/ ) he kindly and very quickly worked out a small programme to solve the problem. If anyone else would like a copy, please let me know. It works on DOS.

So, could who-ever-it-was, let me know and I will send it to them. Alan MODEL ENGINEERING DISCUSSION LIST.
