I would love for that to be built in to Aven, so it could actually highlight the route too (you know the problem, you give someone an inch they ask for a mile). It's something I have wanted when showing someone a survey in Aven; "Show me the route I took". That is not always the shortest route, but much like with Google Maps, it would use the shortest route between control points. Instead, I end up manually copying it into an image editor, and adding a background along the route. (This is kind of off topic for Therion of course, but actually, I would love for Loch to have a lot of the features that I still rely on Aven for, such as selecting stations and splays and measuring between them. So I guess that would be needed first!) ___ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
Re: [Therion] Export centerline and/or stations to SHP without th2 files
Hi Stacho & Martin I ran it with the new release, it world good now. Thanks!

Re: [Therion] Get shortest route
Hi Benedikt and Olly,
I implemented such functionality (not the visualization) a while ago
as a little exercise in Python. If you know how to run a Python
script, then you might find this useful.
First download this file:
https://raw.githubusercontent.com/speleo3/inkscape-speleo/master/extensions/survex.py
Then run this code (replace the file name and station names):
filename = "smk-arge.3d"
station_from = "p87"
station_to = "115.commando.105"
from survex import Survex3D
survey = Survex3D(filename)
length, p = survey.shortestpath(station_from, station_to)
upwards = sum(max(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:]))
downwards = sum(min(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:]))
print("Shortest route length:", length / 100, "m")
print("Cumulated height going upwards:", upwards / 100, "m")
print("Cumulated depth going downwards:", downwards / 100, "m")
Cheers,
Thomas

Re: [Therion] Hiding cross-section symbols
A good idea that I had not thought of! But it won't work for me. I like to use "-direction both" on my section lines. Yes, I could put the direction arrow on one end only, but that is not my work habit. For others - an excellent idea.

Re: [Therion] Hiding cross-section symbols
line section could have more than one segment. Second (third, …) section you may use instead of arrows.
