Hi, I agree with Bruce, that it is really a very useful feature. I have just pushed it on GitHub (see commit 2ebc7ed). The only problem is, that survex calculates error which "is the ratio of the observed misclosure to the theoretical one". I have implemented more simple export (it was much easier), currently therion .3d export contains error equal to 2 * relative error of a loop. (because of 0-12 aven fixed error scale). It should be possible to extract survex relative error from either thTMPDIR/data.err or data.3d file, but it will take some time. But when I compared 3D files with relative loop error and error with survex ratio, I received two quite different pictures. Are these two measures not comparable? Is a relative error of a loop useless number? Has anybody tried to go to a cave and resurvey "red shots", whether they are really so bad? S.

Therion strips most of the data apart from staions and legs out of 3D files it generates. Colour by error and by date are not possible because that information is not in the 3D files generated from a Therion project. Entrances are lost too. One of the reasons I plan to add Therion to Survex conversion into my cave converter program (when time permits).
Therion-generated .3d files now[*] contain date and coordinate system information, thanks to a patch from Vlad:

[*] This isn't in a released version of therion yet, but I'm guessing there's likely to be a new release soon as it's been years since 5.3.16 and a lot of useful stuff has been merged recently.
