this message pertains to state highway department engineers who survey horizontal curves on a regular basis. I have written a program on the 41, 42s, and 48 (all the same program) which, given 3 pieces of data, will calculate an entire simple curve for the purpose of laying in from the PC (BS on PI or back tangent) with a total station. This program can save 45 min. or so key punching. The only catch is that you have to have the IR printer. If anyone is interested, please let me know and I will ask the most honorable webmaster to post it. Any takers?
thank you,
john
