Thanks for the responses! I'll try and clarify what I'm trying to do.
I have a lot of survex data which has been 'converted' to therion data. A file for example might look like this:
==================atlantis.th===================
survey atlantis -title "Atlantis"
input atlantis-p.th2
map matlantis-p -projection plan
atlantis-1p

You can see the original data from the SVX as a comment.
I also have for reference old drawn surveys which were drawn in Inkscape around an exported centerline from Survex. I have the original files for these. I am now trying to redraw these in Therion.
The workflow I have been shown is:
- Use Therion to export an SVG image of the centerline (from atlantis.th)
- Create a blank map file (atlantis-p.th2)
- Open this blank map file in Inkscape using the Inkscape Therion Plugin.
- Import the image of the centerline into the map
- Individually mark stations in the scrap layer by pasting a station object over the stations in the imported SVG image.
- Once stations are marked, draw the passage
- Save etc.
It seems like it should be possible to take the centerline data (from atlantis.th) and export the stations directly into Therion map/scrap to start drawing around without needing this intermediate step of the centerline background image.
