There's a ticket open already: https://trac.survex.com/ticket/80 Julian sketched out what needs doing there, but didn't actually provide a patch (or else I'd have applied it by now). But Therion could do a better job here as it has the drawn passage walls to work from. Cheers, Olly ___ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
Re: [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. -- Bill Gee On Wednesday, August 14, 2019 10:49:32 AM CDT chris pennos wrote: > Hi, I am also interested on volume calculation! > > Please keep me updated it! > > > On 11 Aug 2019, at 22:22, Benedikt Hallinger wrote: > > > > 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? > > > >> Am 09.08.2019 um 14:58 schrieb Bill Gee : > >> > >> 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.

Hi, I am also interested on volume calculation!

Re: [Therion] How to calculate the volume of a cave
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? > Am 09.08.2019 um 14:58 schrieb Bill Gee : > > 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.
