My cave data converter program does this for survex data files (a subset of the syntax is supported at present), and also from DXF files generated from a survex .3d file.<br><br><a href="http://www.darkgem.com/wscc/caving-talk/index.php?title=CaveSurveyDataConverter">http://www.darkgem.com/wscc/caving-talk/index.php?title=CaveSurveyDataConverter</a><br>
<br>You can export any 3D files to DXF from the right-click menu in Windows Explorer if you have Survex installed, and then convert this DXF file using my converter to a toporobot text file which PocketTopo can import. You do lose the original station numbers in the process, but it does at least get the cave centreline onto your PDA so that you can survey new stuff tied into the known cave and have the full network diagram with you underground. I then just export the new data from the PDA after the trip and process it into the drawing program of my choice.<br>

Several years ago Stacho made simple export from Therion to PocketTopo. It created plenty of short series, but it worked. The name of Therion station could be wrote in note field.<br>

Has anyone achieved the reverse?  I&#39;d like to export an existing Therion<br>
survey into PocketTopo, so that when I add to the survey using the DistoX,<br>
I can immediately see the new and the old data in PocketTopo.<br>

A nice idea, and I&#39;m sure it could be done.  PocketTopo is a great tool for<br>
collecting data, but for me it would be like getting back into a strait<br>
jacket.<br>
<br>
I can see issues with survey or &#39;series&#39; connections, station naming, and<br>
station co-ordinates.  In Therion these are completely flexible, we add<br>
prefixes &amp; suffixes to the pockettopo stations, for example, to make them<br>
more human readable.  In PocketTopo they appear to be rigidly constrained,<br>
and I have found odd things happen when I (regularly) bend PocketTopos<br>
rules.<br>
<br>
Good Luck<br>
