Cubic meters as a new parameter in caves documentation
by piotr_szukala 17 Dec '09

17 Dec '09

Hi! I’m trying to apply new parameter in caves documentation in Austrian Tennengebirge Ost and Polish Tatra Mountains. It could occur how big actually is a cave system and could help in a few scientific investigations as a cracks and hiatuses in limestone massif. Is there any possibility to read off cubic capacity in m3 from model 3D? Best regards Piotr Szukała Poland

Cave mapping software and Windows 7 I am planning to install the new Windows 7, and I wanted to ask if anyone has tried some cave mapping programs with it. Do you know if any of these work or don't work with Windows 7? TunnelX Tunnel2 Compass Walls Survex Therion VisualTopo Onstation Speleoliti GHTopo ...

bug report
by Vasily Vl. Suhachev 02 Dec '09

02 Dec '09

Hello I am found some bugs, 5.2.14 XTherion 1) text in "Help->Controls..." for russian translation must be in CP-1251 (now in UTF-8) 2) slash in "command line options" editbox now must be doubled, example: -p ..\\.. 3) scrollbar of side panel initialized incorrect at first time after .th2 file opened 4) jumping from compiler log cause error when jump target (line nember in .th2) denote on line without line points 5) after change point type to "station" the field "orientation" not cleared 6) short-cuts not worked when I switch keyboard to native language 7) points changed their types to "station" when I set them close to XVI station node Therion 1) line command whth one line point cause infinite loop while compiling with message: [Warning: unable to determine direction on zero-length path in scrap S-800-1@] 2) When station connects to other stations which not present as point:station in map(but present in centerline) Therion draw line:survey anyway and some features be good to implement: 1) multiple installations of Therion at one system (at this time second installation to different folder corrupt the first one) 2) new command in thconfig, analogue to "-p" Therion command line option -- WBR, Vasily

Increasing Metapost 4096 scrap limit
by Carl Magnuson 01 Dec '09

01 Dec '09

I am getting close to the limit of 4096 scraps for Metapost which is mentioned in the Therion book and I have ran into it in some cases. It looks like this is a setting in Metapost that must be changed and not Therion, but I was hoping maybe others had ran into this and knew what modifications are needed to Metapost to accept more scraps. Thanks, Carl

-station-names prefix suffix disable
by Bruce 24 Nov '09

24 Nov '09

Hi Is it possible to use -station-names <prefix> <suffix> within a scrap definition, and then disable it for only one or two stations that need to have a different prefix (connecting to a different survey). I have tried using a group endgroup block within the scrap, but get therion.exe: error -- PP-ParaphantaShaftPlan.th2 [248] -- unknown command - group Bruce

Re: [Therion] Incorrectly Drawn Scraps
by Martin Sluka 20 Nov '09

20 Nov '09

Problem from Carl: Posted here http://mbug.dyndns.org/example/ are two thconfig files, one with the scraps and one without and the generated PDF files. The shot B009-B010 for example looks fine in the just centerline export, but does not show up on the export from scraps (even though it has a scrap which looks correct). Analysis from Stacho: All scraps has identical coordinates of stations and in several cases neighboring scraps has identical distance between walls. Therion has one hidden feature - it tries to join scraps automatically if there is no command "join". And in some conditions the result is as in your example. Therion "thought" two neighboring scraps are of one passage. Stacho wrote me the shift of coordinates: for example 0-100, 1-101, 2-102 should help. The problem at the end is in Carl data. (comment m.s.) :) A note: Don't use visibility on/off but subtype invisible subtype bedrock You may not use smooth off when there is no one bezier curve in your data. Correct data: scrap example-11-18-th2 point 0 0 station -name B007 point 100 0 station -name B009 line wall -outline out -attr color "color col; col:=(.5,0,0);" 100 4.62962962962963 0 4.62962962962963 subtype invisible 0 -4.62962962962963 subtype bedrock 100 -4.62962962962963 endline endscrap scrap example-11-19-th2 point 1 0 station -name B009 point 101 0 station -name B010 line wall -outline out -attr color "color col; col:=(.5,0,0);" 101 4.62962962962963 1 4.62962962962963 subtype invisible 1 -4.62962962962963 subtype bedrock 101 -4.62962962962963 endline endscrap Several pictures illustrated the problem:

Version Control Systems and Therion
by Bruce 17 Nov '09

17 Nov '09

Eighteen months ago there was some discussion about VCS that people were using with Therion. We have two largish projects and soon to be three people working on their own copies of the files that every now and again I try to merge into a coherent dataset. I suspect it's well passed the time where we should have been using a VCS, but you know how it is. Sometimes it seems easier to run along pushing a bicycle than it is to take the time to choose an appropriate one, and hen learn to ride it. A few VCS options were mentioned, including bazaar http://bazaar-vcs.org/en/ and subversion http://subversion.tigris.org/ In an effort to get more local people involved and ease the learning curve for Therion newcomers I'm thinking that putting all our data on a web page and allowing those working on it to have ftp access. Bearing in mind that I have no experience with any type of automated version control (am downloading bazaar as I write this) is there any advice out there? Best VCS application to use? Are ease of use for learner computer users, ftp, Therion and VCS mutually exclusive? My (sheltered) experience with ftp so far is that it is no more complex than using files on a local disk. Is this a good route or should I try another path? Any feedback or advice welcomed. Cheers Bruce

Length Units Mile(s)
by Carl Magnuson 16 Nov '09

16 Nov '09

Would it be possible to add a mile(s) distance unit? My big map is getting close to 3 miles and it would be nice to have the total distance in the legend be in miles. I do all my measurements in meters but use feet on the maps, still haven't completely adopted the metric system! Carl
