Hi Bill, Torsten, What is that file; is it a standard output file from Therion or Survex? Best regards Ben Sent from my iPhone

Ha! Torsten, you are a magician. Thanks!
That was indeed exactly how I calculated this. I had completely forgotten about it. Fortunately the data file still exists on my Windows virtual machine, and Compass produces the number I need to defend. I now know how to reproduce the calculation.
Breathing a huge sigh of relief ...

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.
Hi, I am also interested on volume calculation!
Please keep me updated it!

It would be awesome if the compiler could derive this fron the loch model and write it to the statistics block (the one where also loop closure info and total west/east and north/south dimwnsions are returned) when compiling this, as the neccessary data should be already present?

Hello everyone -
What tools can be used to calculate the volume of a cave based on center line and LRUD data?
I found an email from Martin Sluka from about 4 years ago describing how to use Loch to export a .lox file in other formats, then run that file through CloudCompare or ParaView. 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.
As far as I can tell, Survex does not have a way to calculate volume.
Could it be done with a KML file and Google Earth?
