Hi Kevin, You could definitely use QGIS to do that, and probably export in a format close the the one used by Therion. I’m using directly GDAL command lines to convert in a format similar to the surface file for Therion, I can dig in my files to find the command line. But I don’t know if you can use directly the GDAL command lines with windows OS.
