[Therion] Therion 6.0.5 more on volume calculations

[Bill Gee]

A neat new feature!  Thanks!

However, I am reminded of the old adage - A man with one watch always know the time.  A man with two watches is never sure.

Using a rather simple 50 meter cave as an example, I now get four different calculated volumes.  Three of them are at least in the same ballpark, but one is about three to four times greater than the others.  

Compass = 5931.1 cubic feet
Loch LRUD volume = 3754.1 cubic feet
Loch Maps 3d = 6106.8 cubic feet
MeshLab = 586.9 cubic meters (20697.9 cubic feet)

MeshLab is an outlier here.
