[Therion] Importing Survex files

[Graham Mullan]

Owing to some features of my dataset, including, as I have flagged up 
before the fact that Therion is not as flexible as Survex when it comes 
to data entry, in that it requires a clino column even when the data has 
not been collected, I am still having to import some survex 3d files 
into my model.

I also use Survex to view other people's models. This data has been 
compiled in Survex 1.1.15 as it includes passage dimension data. The 
problem is that 3d files compiled using 1.1.15 instead of 1.0.39 will 
not import into Therion.

Is there some way that this can be dealt with so that I don't have to 
keep installing/uninstalling versions of Survex?
