Topodroid (or other digital) survey to Therion Process?

I was wondering if anyone had any best practices for getting data from a digital survey device into Therion quickly and easily. I've just modified my process AGAIN. I think I'm getting closer to a good process, but am curious if someone can save me some steps.

1) Export from Topodroid to .th, .th2, and .svg. (I also export .png and .cvs so I can show it to my paper surveyors immediately).

2) Open the .svg file in Inkscape (running the Therion extension).

3) Create a new layer in the .svg file to re-draw the sketch using my wacom pen on my tablet for higher quality drawing.

4) Re-draw the sketch much more carefully and using the Therion extension on each line (I.E. to make a line ceiling-step or rock-border or floor-meander).

5) Save-As a .th2 file.

6) If needed, I open my .th and .th2 files and add a prefix to the station names using the code "station-names MyPrefix_ []"

7) Add the .th and .th2 files to my master .th file.

Ideas on methods to save time and prevent errors would be greatly appreciated.

Simplest and best way is to use Andrew Atkinson' s TopParser. Don't have  the download link to hand, will post it when I get back to my desk.

It takes .top files and converts them into several different formats. Immediately outputting various useful things.

.3d file for use with Aven (survex), so you can see the relationship with other systems. Edit 10.34
.th and .th2 files which are used by Therion to build a therion based Cave survey. (other cave surveying software is available)

It is ultimately useful for building your filing system for Therion.
