Hi, I have create the following 52 new symbols for Therion: Therion symbol set Topodroid symbol group Points: altar EGB anthro archeo-excavation EGB extra audio EGB extra bat EGB extra bone EGB extra curtains UIS extra danger EGB speleo disc-stalactite UIS extra eletric-light EGB anthro ex-voto EGB anthro gate EGB anthro helictites UIS extra human-bone EGB extra masonry EGB anthro minus EGB speleo mud EGB speleo mud-crack EGB extra nameplate EGB anthro pendant EGB extra photo EGB extra pillar-with-curtains UIS extra pillars-with-curtains UIS extra plus EGB speleo plus-minus EGB speleo seed-germination EGB extra stalactite-stalagmite UIS extra stalactites-stalagmites UIS extra tree-trunk EGB extra volcano EGB extra walkway EGB anthro walkway-metalic EGB anthro walkway-soil EGB anthro walkway-stone EGB anthro walkway-wood EGB anthro water-drip EGB speleo Lines: abyss-entrance UIS extra dripline UIS extra fault UIS extra joint UIS extra low-ceiling UIS extra pit-chimney UIS extra walkway EGB anthro walkway-metalic EGB anthro walkway-soil EGB anthro walkway-stone EGB anthro walkway-wood EGB anthro Areas: mud-crack EGB extra pillar UIS extra pillar-with-curtains UIS extra stalactite UIS extra stalactite-stalagmite UIS extra stalagmite UIS extra I would like to offer them to be included in Therion's source code. My suggestion it to incorporate them Therion distributed in 2 symbol sets: the existing UIS one and on a new one to be called EGB. The ones to go to UIS have their images inspired by similar symbols from UIS. The ones to go to EGB are ones that I can't identify some already existing symbol set to receive them so I am proposing a new symbol set named EGB (for Espeleo Grupo de Brasília = Brasilia's Speleo Group, my speleo group) as many of these symbols were demanded by some fellow members of EGB. This is my suggestion but obvioulsy we can choose any other path, for example: - distribue them differently among symbol set's; - incorporate just some of them in Therion's source code; - not incoporate any of them (I would distribute them as stadalone files to be used by the interested parties as user symbols). As I mentioned, we can follow any prefered path. Please let me know if the idea is to incorporate them in Therio's source code, as I would have to adapt them because, right now they are formated as standalone user symbols. Please advise. Regards, Rodrigo Severo P.S.: The "Topodroid symbol group" mentioned on the table above is the symbol group where each symbol resides in Topodroid. I bet this info isn't actually relevant to Therion but I decided to include it for completeness.

Breaking a loop at a specific station on extended elevation
by Tarquin Wilton-Jones 21 Dec '19

21 Dec '19

Hi folks, There are a few of us who are struggling with an extended elevation problem. I have attached a sample data file, which represents the data from a real cave. There is a main passage (stations 1-2-3-4-5-7), and a high level oxbow (stations 2-6-5). Because the oxbow is shorter, Therion defaults to using that as the primary extended elevation path, which is not desired. The natural (human preferred) way of extending that, is to show the main passage as a single line, then have the high level oxbow split at station 6, with a leg pointing to each of the two stations it connects to, and a dotted line connecting the two versions of station 6. Like this (if your email client shows this with a fixed width font): 6....6 / \ 1--2--3--4--5--7 We tried various "extend left" "extend right" and "extend ignore", and we managed to make it break station 2, but it seems not to want to break on station 6. (We can obviously break it in the right place by breaking the data, but that is not the intention is to keep the data valid.) Can someone please tell us the magic formula of extend commands that will produce the desired output? Thanks for the assistance. Tarquin

Shortening long passages in extended elevations
by Tarquin Wilton-Jones 20 Dec '19

20 Dec '19

Hi all, With extended elevations, you might want to show only the most important parts, like pitches, while showing long passages as a shorter distance with a break symbol. Imagine a cave with an initial pitch, a long passage, and a final pitch, where the extended elevation should concentrate on the detail of the pitches only, and not have the long passage wasting space. For a real example, see this rigging topo: https://cncc.org.uk/caving/topos/download-single.php?id=6 If the passage is horizontal, you could easily achieve this by setting the legs of the long passage to "extend vertical", so that its stations to not take up any horizontal length. You can then manually draw the gap with some lines. However, if the long passage slopes downwards, this will make the two parts of the passage break with a vertical gap between them. This makes sense because it means that the extended elevation will show the vertical range of the cave, which is great if that's what you are hoping for. But in a rigging topo, it is less useful. There is no equivalent that I can see to "extend equate 21 57", which would be an equate that happens only during an extended elevation. Essentially, this is the desired outcome though. For a real example, see this rigging topo - the breaks represent a passage that has lost as much as 20 metres of altitude, which is completely ignored: https://cncc.org.uk/caving/topos/download-single.php?id=61 One method I can think of - but it feels like a hack - is to draw the upper pitch in one map, and the lower pitch in another map, then use map offsets to pull the lower map into the desired position when rendering. Does anyone have a better solution to this? Can "extend hide" do something useful or will that still keep any vertical (and horizontal) offsets? Thanks for any advice. Tarquin

problem with -flip horizontal extended elevation scrap
by עמרי גסטר 20 Dec '19

20 Dec '19

Hi everyone, I have a scrap of extended elevation to left and I want to flip it so it will be to the right, but when I add -flip horizontal to the scrap definition it flips it upside down and mashing up the lines. -flip vertical does the same thing. am I missing something? my file is generated from Topodroid I added an examples of what it does and the .th +.th2 files -- Omri

Software issue
by Gareth Davies 18 Dec '19

18 Dec '19

All, I've bought a new touchscreen tablet running Windows10 with the thought it might make the drawing by up easier than on my old computer. I can't seem to get the software to load, I've enclosed an image of the screen error. I'm hoping someone here will have an idea what may be going wrong here. Best regards Gareth Davies

Stupendous symbol effort
by Bruce Mutton 17 Dec '19

17 Dec '19

I just noticed yesterday's development update. An amazing effort Rodrigo, adding all of those new symbols. They will be much appreciated I am sure - I can already think of existing maps of mine that I might update as a result. I don't want to be too picky, but I wonder about the use of plural 's' in for some of the symbol names. I have attached a screenshot of the Therion Book page 24. I think symbols such as 'discs-pillars' should instead be named 'disc-pillars'. But of course English being English there are exceptions to the pattern, such as 'pillars-with-curtains' and 'stalactites-stalagmites' which are probably OK. Bruce

How does Therion decide which passages to put above and below
by alastair gott 14 Dec '19

14 Dec '19

Hi Therion guys, In the final throws of getting a report done for Spanish Gov before the end of the year. I need to know how therion decides which passages to put above and below others. I've got higher passages appearing below lower passages, I've moved them around in the map structure, to no solution. So I just want to know If anyone had any insight as to what I should try. Specific example for SVN users here: http://cave-registry.org.uk/svn/Andara/Tresviso/Nacimiento/therion/ Claphamjn_Partingfr.thconfig<http://cave-registry.org.uk/svn/Andara/Tresviso/Nacimiento/therion/Claphamj…> is the config which runs the main survey below. Both side passages (north of main) should be appearing above, hence label "drop to streamway" [cid:95d33f93-2e49-45d7-bd39-24f54233d3af] Regards, Alastair Gott.

Setting -outline for pit lines
by Tarquin Wilton-Jones 12 Dec '19

12 Dec '19

Hi all, Feeling like a beginner here with a very simple question, but oh well... "-outline out" is for outer walls "-outline in" is for pillars in the middle of a passage When a wall line is drawn in the wrong direction, you hit "reverse" to make the little tick point inwards. Easy. Until you hit this wording in the old tutorials: "The "outline" option specifies on which side of a line there is the rock." With a *pit* line that is being drawn with its tines facing outwards - as in, the scrap ends at the top of a pitch - the little tick also points outwards, in the opposite direction to most wall lines. ____________________ |- Scrap to pitch head |- A different scrap starts below the pitch ____________________|- Therion doesn't seem to care whether you set "-outline" for that pit to "out" or "in", the result is the same in most cases when creating PDF. Except when creating a .lox file, where it will complain about the scrap outline being invalid if you use "in". So what is the correct value for -outline on a pit with the tines pointing out, when the scrap outline should be the pit's line? And if it is "-outline out", then why do we always draw walls with the tick pointing inwards - surely if it is valid for a pit line to have the tick pointing out and "-outline out", then it is also valid for wall lines to be drawn that way too, so why don't we? Cheers, Tarquin

Therion/loch crashes in sid (issue #158)
by Benedikt Hallinger 11 Dec '19

11 Dec '19

Hi Olly, i hope you can help me out with issue #158 (https://github.com/therion/therion/issues/158) I am fiddling around in hope to get my loch viewer working again. It worked in the past but then decided after a debian update to cease functioning because of failing glx context. I now have the impression, maybe wxWidgets is the cause. The glx context is fine, other X applications can successfully establish 3D perfomance and glx debug commands also tell me „ok“. I habe seen that there is a wxWidgets 3.1.4 out there. Maybe this could solve my issue? Can you please make me an updated debian package (or tell me how i can build it myself)?
