[Therion] How to calculate the volume of a cave

Update:  After poking around a bit, I discovered that Compass will calculate cave volume based on centerline and LRUD data.  Doing that means I have to run a Windows computer (ugh!) and type in the survey data twice (double ugh!)  Fortunately the cave for which I need this is small.

Can this feature be added as a suggestion for future versions of Survex?

Compass does quite a few other calculations.  For example, it will calculate the volume of the bounding box.  A sample report is attached.  It is nice that the report is in both meters and feet.

The process looks very complex to me, and besides - Loch does not run on my computers, so there is no way for me to generate an export.
