I have a quick and dirty script that sort of already does this. I'm currently not at home but will post what I have on my return in a few days. Documenting and improving it has been on my list of things to do for a while now Andrew On Sun, 26 May 2019, 20:18 Tarquin Wilton-Jones via Therion, < therion@speleo.sk> wrote:
Do you have stations in all the sections?
I do not need this, but I could - I have tested and it would work with multiple stations in the cross section.
I was planning to create the sections after exporting an XVI, rather than using any existing cross sections (though it would of course be nice to know if an existing cross section could be used - I am sure other people wanting to do this will want to use existing cross sections). I can in fact think of a way to use existing cross sections like that, by copying and moving them into position with the exported points, so it is not impossible. It would of course be nice if it were easier, but I can work with it as it is.
source “cystanog.th" export map -projection [elevation 355] -fmt xvi -output “centerline.xvi"
The biggest issue with this is that there will be 2500 stations in that exported centreline. The cave is extremely linear, and when projected on a bearing of 355 (which is what I need for the cross sections), they are almost all in the same 3 locations. So many that it is almost impossible to find the 3 stations I am interested in, and even harder to find the splays that relate to them. See the attached images.
This is why I wanted to export only the 3 stations and related splays, so I can actually see what to work with.
If you use it as background image and create a scrap in which only those three stations and profiles will be defined and exported map with that scrap, you receive what you need. Not use point station in that scrap, and set its projection as none. I’m not sure what it will do with scale option in layout.
Then input the .th2 file with that scrap to .th file and use in plan scraps for section the name of that scrap as reference.
It should work.
Exactly what I was planning to do, yes. Good, so I am not insane :) Thanks for confirming this technique. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
