"\legendbox" "\loadpicture" and absolute paths
by rowena 14 Mar '21

14 Mar '21

Hello, I am using the "\loadpicture" capability in "\legendbox" constructs to include map sections, elevations, etc. It all works nicely on my PC where I am using relative paths to the pdf files. My club has a desire to archive the map data for posterity - ie if my pc dies or I go walkabout, the map data should still be available so that others can add to the maps as they are extended. I would prefer to have the images included using relative pathnames, rather than absolute pathnames, so that future explorers can download the map data and extend it, without having to duplicate my file hierarchy. How can I include relative paths in the \loadpicture functionality? Thanks, Rowena

Scale dependant error when using area fills
by Tom Foord 20 Jan '19

20 Jan '19

Hi all I'm having some problems compiling a project which includes debris area fills. Depending on the exact symbol fill that I use, I am getting strange scale-dependant errors which seem to cause the compiler to loop endlessly until I force it to stop. I originally noticed the problem when using a custom area fill that I made by modifying the standard a_debris_AUT symbol fill. I've attached my modified metapost definition in the attached text file 'a_debris_WUG.txt'. The error occurs for any scale between 1:2000 and 1:4483 (outside of this range the project compiles fine). See attached output log 'Output log - a_debris_WUG.txt'. As you can see, the file seems to loop over and over again. Initially I thought this problem was specific to my custom fill, but then I noticed that I also get a similar error when using the standard a_debris_AUT fill, however this time the error only occurs when the scale is set to exactly 1:2000 (any other scale seems to be fine). See attached output log 'Output log - a_debris_AUT.txt'. Can anyone help with this problem? Thanks Tom

Import a scrap into another scrap (or th2-file)
by torstein finnesand 11 Oct '17

11 Oct '17

Hi fellows, Sometimes I realize that two scraps should have been one (for instance scrap A in A.th2 should have been a part of scrap B in B.th2), in particular when it's difficult to join them. It's easy to insert the xvi file into the scrap B file. But I have to draw it again. Is there any workaround here? Torstein Finnesand Norway

Hi, Here is the link to all class material of a portuguese course I taught on DistoX + Topodroid + Therion: https://goo.gl/YsDLhk I wonder how could I make it available through Therion's wiki page. Regards, Rodrigo Severo

Question/Problem with customizing text labels
by Torsten Schnitter 21 May '17

21 May '17

Hi all I have a question concerning customizing text labels. Drawing a map with scale 1:250 is ok. Just some points a very small on the map. Therefore I would like to resize these points and make them bigger. For example: "point x y passage-height -value [- 10 m]" generates the wanted symbol, a number with a frame around. But it's to small (attached picture passage-height-1.jpg). I add the option "-scale xl". Now it's a little bit bigger but still to small (attached picture passage-height-2.jpg). Finally I use within the layout command: code metapost fonts_setup(6,8,10,14,36); endcode Now the number is looking good in size but the frame around is not correct anymore (attached picture passage-height-3.jpg). Is there a solution for this problem? Or is there any other option to resize single points or lines (like "point passage-heigt" or "line label" ...)? I'm looking forward for any help. Thanks, Torsten

Aven colour by loop error
by Bruce Mutton 05 Apr '17

05 Apr '17

Following on from this thread <https://www.mail-archive.com/therion@speleo.sk/msg04871.html> 2.5 yrs ago where I was asking about Therion support of Aven features. Therion files exported to .3d format now display 'colour by' depth, survey date, gradient and leg length when viewed with Aven. But not colour by loop error. Is 'colour by loop error' something that could readily be added to the Therion export? Bruce

Depth seems to be including surface legs
by Duncan 02 Apr '17

02 Apr '17

We surveyed the surface above an old mine to get a feel for how thin the roof is. See attached Loch screenshot. Unfortunately, the surface legs are being included in the Depth value displayed on the Plan PDF (see attached). Displayed value is 13m, it should be about 8m. 13m is the maximum vertical extent of all our survey legs. The centerline data for the surface legs has been flagged as "flags surface". These have been correctly omitted from the cave length, and cave length is updated when the surface flag is commented out. However, the vertical range does not alter when the surface flag is toggled. I expected cave depth to be the maximum vertical range of the underground data. Hope someone can set me straight :) Duncan

How to add authors of paper drawings, which is being digitized as therion scrap?
by Nikita Kozlov 01 Apr '17

01 Apr '17

Consider following task: Digitize old paper drawings of cave survey and include information about person who did digitizing and person who did drawings on paper. How it should be done correctly with therion th2 syntax? Are multiply -author command within same scrap supported (Ie oldest date corresponds to paper drawing, newest to digitising)? With best regards, Mykyta Kozlov.
