Survex .3d files record the coordinate system the data is in, if one was specified. This was added in Survex 1.2.14 (released 2014-07-05). But looking at the therion source code, it appears therion never makes use of this information. I suspect therion just hasn't been updated for Survex gaining coordinate system support. You can specify the coordinate system as an option to therion's import command, so for now I guess that's what you have to do.
