Yep, that would work, but Therion is meant to work with the survex data formats, so the nosurvey should work. It looks a bit like a bug, or I am using wrongly. If no survey is not supported, that is fine, it is not critical. My solution would be to put a false leg in and not that nearly hit and accept a small gap. This would not case any false distortion but I prefer the idea of nosurvey. Andrew On 10/06/10 21:19, Bruce wrote:

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.
