Hello, and merry christmas! I currently try to correct some old surveys without altering the original data. The manual proposes the "revise" command to accomplish this, at least i interpreted it like this. The problem with the old data is, that the declination setting is wrong but i dont have write acces (archive). I now want to add a revise section so it remains obvious what the original data looked like. This does not work however, it seems that it is just ignored and produces the same aven-3d model... What am i doing wrong? Here comes some test data. My ultimate goal would be to have the revise section in a separate th-file where also all my maps/scras are referenced. -------------------------------------------------------------------------------------------------------- encoding UTF-8 survey test -title testsurvey centreline -id zug_1 date 2007.11.02 declination 0 degrees # bad declination here on purpose, should be "revise'd" later units length meters units bearing gradient degrees data normal from to length bearing gradient left right up down flags duplicate 1.AP1 1.A 23.25 292 -7 0.5 0.5 0.5 0.5 1.A 1.B 5.2 111 11 0.7 0.3 0 1 flags not duplicate 1.B 1.1 11.8 185 22 3 0 5 1 1.1 1.2 7.85 160 -30 2 2 5 1.5 1.2 1.3 16.1 160 90 0.8 0 5 0 1.3 1.4 19.8 233 81 0 0 0 0 1.4 1.5 7 40 10 0 0 0 0 1.5 1.6 21.8 140 70 0 1 0.5 0.5 endcentreline # correct declination setting # NOTE: This seems to not be functional.... neither of both work as expected revise zug_1 # declination 90 degrees # try one: adjust declination # calibrate compass 90 # try two: adjust compass calibration endrevise endsurvey test ------------------------------------------------------------------------------------------- Thank you in advance!
