How do you draw objects outside cave?
by Nikita Kozlov 08 Jan '16

08 Jan '16

Hi everyone! What trick can be used to draw cave objects like rivers, trees outside actual cave like here: http://www.thailandcaves.shepton.org.uk/files/cavesurveys/chumphon/cp0054-t… (a piece of river near Resurgence entrance) Drawing invisible walls did not help me. My rivers always gets cut by line connecting entrance sides.

If it simply sent html-only mail, then at least my end will translate that and show me something. But sending an explicit text part that is actually empty is completely broken. ] And we'll stop bothering everyone with this now as you seemed to have got it to work Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/

Online interactive survey of 58km system
by Footleg 06 Jan '16

06 Jan '16

I thought people on this list might be interested in the latest presentation of the 58km system survey I have been working on. I have just added the first part drawn using Therion (the colourful bit around the Carcavuezo entrance in the middle of the southern edge). This survey assembles the best data over 40 years, featuring 'pencil and graph paper', 'ink on tracing paper', 'offlet litho printed', Tunnel and Therion software drawings. http://wscc.darkgem.com/matienzo/4valleys/ This format should work on all mobile devices and web browsers on computers.

Loch settings and language
by Владимир Георгиев 06 Jan '16

06 Jan '16

Hi Is there any way to make Loch remember the settings for what to show in the scene, walls, type of station names, comments, etc? Or does Loch always use some hardcoded values? Also, is it possible to the UI language of Loch? It uses Bulgarian, which is the default for my Win, but I would rather switch to English from time to time. Thanks Vladimir

Rope line
by Владимир Георгиев 05 Jan '16

05 Jan '16

Hi I was trying to add a line:rope to a map, but without any success. In the data.mp file I see there is a definition of the "l_rope" line, which is equal to the "l_rope_SKBB", but the rope line I drew didn't appear with either the UIS or the SKBB symbol-set. I also tried including some metapost code in the layout to define the line, but again without result. The metapost worked for other line types like ropeladder, but not for rope. A workaround is to define a custom symbol "u:rope", but I wonder why the built-in one doesn't work. Any ideas? Vladimir

Hi, The attached files are the first draft of a translation of Therion into Mandarin Chinese. It is based on the texts and xtexts files from version 5.3.16 of Therion. Many thanks to Zhang Yuan Hai (张远海) of the Institute of Karst Geology in Guilin for most of the translation. Reports of any mistakes will be gratefully recieved. Happy New Year! Duncan Collis

compilation patches
by detrito 29 Dec '15

hi list, I wrote some patches in order to compile therion (and loch) under archlinux. they are not well written, but it would be nice to see something similar in a next release ;) they works as follow: cd "${srcdir}/${pkgname}/loch" patch -p0 -i ${srcdir}/loch-makefile-vtk-6.1.patch cd ${srcdir}/${pkgname} patch -p0 -i ${srcdir}/makefile-install-path.patch make make DESTDIR="${pkgdir}" install cheers, detrito -- gpg --recv-key 0x88D6D3C6

Re: [Therion] Best practice - orientation of original sketch? (Bill Gee)
by Graham Mullan 27 Dec '15

27 Dec '15

Bill Gee said: "My solution is to choose a map rotation early and stick with it, and also to not put images on the map until almost the last step." This presupposes that the cave will never be extended again, especially in 'unexpected' directions. Let us say that North up is chosen as a map orientation. Let us then say that before the known cave has been completely mapped a large extension is discovered that trends south-west. Then another one is found elsewhere in the system that trends east. It may be that the convenient orientation of the map will change during the course of the project. To Therion users this does not matter one jot as Therion will always rotate stuff as required. And I don't know about anyone else, but especially in complex projects I have always to return to .th2 files to tweak the exact positions (and sizes, sometimes) of labels in order to ensure best fit in the final drawing. Thus I would always (if being forced not to use a PDA for some reason) survey to use pages to their maximum extent and put up with the minor inconvenience of reading sideways whilst drawing up scraps, 'cos whatever you choose, arbitrarily, you will always be wrong at some point. As an aside this is also in part why we try to generate the finished product as a pdf directly from Therion rather than importing into another drawing program as it cuts out the need to do parts of the job twice. The drawback with this is that Therion is not quite yet as flexible as I would like, notably in the management of colour and in the availability of different fonts and text characters (ampersand, copyright symbol etc). I know - or suspect - that some of these latter issues might be solvable in MetaPost, but I'm a rubbish programmer who can just about cope with php and html but no more. Graham

Best practice - orientation of original sketch?
by Bill Gee 26 Dec '15

26 Dec '15

Hello everyone - This is not really a Therion question. It is more of a general survey question. Therion is sort of involved in the situation, though ... When you are drawing the sketch in the cave, is it normal to ALWAYS make north the same direction on each sheet of paper? What is considered "best practice" in this regard? Background: I have been helping with survey of a cave that has grown to slightly over 5000 feet as of a week ago. I have been both sketching and doing cartography. Therion is my weapon of choice! :-) At least 6 people have done some part of the sketching in this cave. All of us have oriented our sketches so as to best fit each section of cave onto the paper. We always indicate north, but it can be any edge of the paper. The man who is coordinating the project is also doing cartography using Windows tools (Walls, Xara, etc.) He sent me an email today asking if I will commit to making all future sketches with north being the top of the page. He asks because some of the computer work he does results in portions of the sketch being upside-down and therefore more difficult to read. Thanks - Bill Gee
