It seems to be a bit streng to ask help for that, .. sorry. Can someone help me ? Thanks again, Gilbert

Re: [Therion] Cave length discrepancy
by Graham Mullan 23 Sep '12

23 Sep '12

Update it looks like our cave length problem was down to a couple of small segments being left off the map as they hadn't been drawn onto the plan. In our defence, that's as they are near vertical blind pits that had been surveyed separately to the bit of cave above them. Graham

Cave length discrepancy
by Graham Mullan 23 Sep '12

When generating a pdf for one cave, the automatic title reports a slightly shorter length than that reported by X-therion. Has anyone else had this? Graham

Box round offset
by Andrew Atkinson 23 Sep '12

23 Sep '12

Hello I have been using the map-connection point to link my offsets, which is great. However one Cave I am trying to efficiently get onto one piece of paper, would benefit from having a box around where it comes from and where it goes. I have tried a few ideas but all the lines only appear on the offset. The best way I have found is to draw it in as another scrap which is not offset as well as having it in an offset scrap, but this is messy. It also gets rotated by the declination, but I was hoping no one would notice this when it is printed. Attached is what I am trying to do (I probably need to place it somewhere better) Is there a better way of doing it, if not, could I add this as a feature request that there is a line type, that is drawn on both the original position and the offset. thanks Andrew

New file error
by Andrew Atkinson 21 Sep '12

21 Sep '12

I have just discovered a frightening bug If you hit the new file icon (as I did accidental because my menus had disappeared. as I tried to open the file menu) the object window on the right is cleared, but not the picture. (So when I first did this I did not notice, and carried on, only noticing when I tried to compile it and it failed but I had over written my file by then, thank you version control, only lost half an hours work.) Anyway, recreating this, it appears that after you have hit new file (the icon) the Object window is cleared, and if you then click on a line or point in the drawing window, it adds an end of file and then the object appears after the end of file, item number -1. anything else click continues to be added as -1. trying to click on these objects in the object window, gives an error (I was hoping to move them to the right side of the end of file). Adding new items go in the right place and then anything clicked on is put in the right place but still with a -1 number, selecting this in the object window puts in a new end of file line, directly after it, therefore loosing everything else. I have attached a screen shot that hopefully show a bit of what I mean. Therion 5.2.9 on Debian whizzy Andrew

KML model in Montenegro
by John Stevens 21 Sep '12

21 Sep '12

I have been trying to create a model of an area on Montenegro. This area uses a local map system VGI which I thought was EPSG:3908 origin 18 degrees E scale 0.9999 false easting +6500000 false northing 0.0 Dx +653 Dy –212 Dz +431 Da +740 Df –0.00010441 When I use these in a gps (user grid etc) they produce the correct VGI coordinate to match the maps. I successfully produce a kml file but all the caves are about 400 east of where they should be. Is EPSG:3908 useable in Therion? A second little point, that I may have seen somewhere and now lost. How do you mark an entrance to show up as a point on a kml file I have used this for the lox output fix 1.0 6559346 4713067 766 # comment station 1.0 "GK103_SS" entrance John

Splays in pdf plans

Thanks Bruce, this gave me the hints I needed to do it. So I was including the survey file in the map, but that did not work. Still only got the centreline but no splays. I am also using pockettopo data with - as the to station. What I was doing wrong. I only had one map in the file so was allowing therion to do its stuff with no select option in the config file, also as the map has map information you do not need to use -proj plan, it just works. So to get splays displayed as the 'default' you need to select the map it is in (possible a high level one would work but I have tried enough for now) and explicitly have -proj plan on the map group, otherwise you only get the centreline. thanks Andrew

Therion wiki
by Ladislav Blažek 19 Sep '12

19 Sep '12

Hi all, when I was creating new wiki page yesterday I realized that we are completely missing some conception/structure in our wiki. A lot of tutorials mixed with various tips and tricks, examples, FAQ... I spent several minutes on wiki and I found a lot of really good stuff... A lot of good tips pretty hidden (not only) for newcomers. So maybe it is good time for some clean up and consolidation. My proposal is to divide documentation to few sections: - Guides and tutorials - Tips and Ticks - short tips like Checking of Therion "environment" - Code snippets (TeX, MetaPost) - Operating system (OS) related tips - installation, configuration etc. - Related stuff - tools, svg to th2 etc. and consolidate the rest = move pages into sections, split or merge some pages etc. Is there anybody willing to help with wiki maintenance? Another question is about bug tracker and IRC channel. I don't think it is used so is there any reason to keep links on main wiki page? As I am hosting whole project on my VPS we can have whatever we need - maybe some really simple bug tracker, VCS etc. hosted on speleo.skdomain. Any comments and suggestions are more than welcome. L.
