First, open you th2 file : you have drawn the walls, but you do not have makes any stations. I think that the mistake comes from that. Maybe I am wrong, but if i have good understood the way Therion is working, for each scrap, you need to plot the stations (using the point "station", and having the option -name 5@testmine_03.testmine for instance). This the way to clip the drawing to the survey.
many thanks (and to Martin), this is the cause, I think. I had not known about necessary stations at all. I have tried to insert stations, but option | --name 5@testmine_03.testmine yields an error: | therion: error -- testmine.th2 [10] -- survey does not exist -- | testmine_01.testmine -- station does not exist -- 2@testmine_01.testmine If I shorten this to --name 5@testmine_03 it works. I have read in the wiki, that (obviously) two stations are necessary to compute the scale, but if I do that in each scrap, the resulting pdf is heavily distorted, very much so in the free-drawn scrap. I have not found out how to add, as Martin wrote, manual calibration (scale), bit frustrating. Well, an example would take me a long way. Please, can anyone point me to a lrud-survey example with good stations, or, even better, can insert working stations in this testmine survey to see? I promise to write a "miner's beginner guide to Therion with pitfalls" doing the next survey, so others may profit also :).
An other comment : in your *.th files, you define both date 2016.05.16 and then declination -2 degrees If I good understood, the « date » option gives the date of the survey, not the date of the drawing (for that, you have to add it in each scrap of the *th2 files). This date is used to correct from the declination. In consequence, you do not have to add the declination -2 degrees after the date option if you have set it well ;-)
Thanks, will use that, much better! Best regards, Christian PS. If anyone has a litte time for an example, would be most grateful: http://kartan.de/div/scaling_mishap.zip http://kartan.de/div/scaling_mishap.tar.gz
