Unhelpful metapost error
by Olly Betts 14 Oct '04

14 Oct '04

My, I'm all questions today... When I try to process my survey to produce a PDF plan, metapost appears to not like something, but there's no error message, so I've no idea where to look. I've attached the log, I can send other stuff if that's helpful. This is therion 0.3.3 on Linux, with THUSESVX defined.

snow and ice
by Olly Betts 30 Sep '04

There doesn't seem to be a way to make an area "snow and ice" (the UIS symbol for either is stars). Does this entail writing some metapost? Has anyone already done it? Cheers, Olly

Example models?
by Wookey 30 Sep '04

30 Sep '04

I'm giving a talk about Therion at the BCRA conference this weekend. Are there any examples of real 3D models and how to create them beyond the piccy on the website? Is this functionality actually in therion 0.3.3? Can it do colour in surveys yet? If so how? Is morphing restricted to within a scrap? e.g. say I have two parallel passages, the data for one changes so it morphs. If they are drawn on the same scrap then the walls of both passages will move. If they are on separate scrpas then only the one that changes moves - correct? i..e morphing is done on a 'distance from station, within a scrap' basis? Can someone explain what the numbers and arrows and things in the bottom of the atlas view are for? I've pressed a lot of buttons and the view changes but I have not managed to understand exactly what is going on in terms of levels, names, links and grid positions. (I am looking at the cvs cave_a.pdf example) I'm leaving in about 1hr so any quick answers ytou have would be good :-) Wookey -- Aleph One Ltd, Bottisham, CAMBRIDGE, CB5 9BA, UK Tel +44 (0) 1223 811679 work: http://www.aleph1.co.uk/ play: http://www.chaos.org.uk/~wookey/

How to change settings for just a few readings?
by Olly Betts 29 Sep '04

29 Sep '04

I'm looking at how to convert from .svx format to .th format. Mostly working, except I can't see how to handle this cleanly (the situation modelled here is that the tape is too short, and for one leg is was measured from a different point - in the example this was distilled from because 2-3 was a plumb and we needed more tape to tie a crab on): *begin test *calibrate tape 1 1 2 10 0 0 *begin *calibrate tape 2 2 3 10 0 0 *end ; *calibrate 1 is now be back in effect 3 4 10 0 0 *end test The nearest I can get is: encoding iso8859-1 survey test -title "test" centreline calibrate tape 1 1 2 10 0 0 endcentreline centreline calibrate tape 2 2 3 10 0 0 endcentreline centreline 3 4 10 0 0 endcentreline endsurvey However this doesn't restore the "calibrate tape 1" of course (the survey length is 27m). I can't omit the survey name for a survey command, or pass an empty name. And I can't nest centreline commands. The only solution I can see is to track which settings are in effect and reset them all after the *end. That's just about OK for automated conversion if nobody's going to want to edit the result, but it must be a right headache for anyone who has tried to hand convert a dataset so I'm wondering if there's some way to express this situation. Cheers, Olly

demo-rabbit doesn't process
by Olly Betts 10 Sep '04

10 Sep '04

Using the therion 0.3.1 debian packages, I unpacked demo-rabbit from the tar.gz file, ran xtherion, File->Open thconfig from the demo-rabbit directory, and then File->Compile. This stops with an error - the full output cut and pasted from the lower frame is: therion 0.3.1 initialization file: /etc/therion.ini reading open file -- /etc/therion.ini close file -- /etc/therion.ini configuration file: thconfig reading open file -- thconfig close file -- thconfig reading input -- rabbit.th open file -- rabbit.th open file -- rabbit.th2 therion (therion.cxx:332): error -- (thdatareader.cxx:213): rabbit.th2 [708] -- (thline.cxx:370): invalid number -- horizontal Line 708 of rabbit.th2 says "adjust horizontal". If I remove this, I get an error for a later line which says "adjust vertical". Searching the manual for "adjust", "horizontal", or "vertical" doesn't turn up anything useful. Cheers, Olly

Therion 0.3.3 announce
by Martin Budaj 10 Sep '04

10 Sep '04

Hello everybody, therion 0.3.3 is available. The most important changes are * support for surface map (2D) and surface grid (3D) * it's possible do display centreline in 2D map without drawing the scrap (it's enough to include survey in the map command) See the file CHANGES for details. The web page contains screenshots illustrating new features. Best wishes, Martin
