Andrew I can only think of somewhat lateral solutions to this. 1. Make the measurements between the stations (You seem to be using a distoX based on the data format), or 2. Replace the nodata line with; station 2.1 "Can see stn 2.9 from here" and then make your drawings using Xtherion with this in mind, or 3. Make a guess at what the measurements are between the points, and do something like making your survey grade BCRA5 and then; group grade BCRA3 <your guessed measurements here> endgroup If this distorts too much you could use sd to lower the dependence on the guessed data. Based on my trials a year ago this can be very effective. Bruce
