Hi all I'm using Therion 5.3.16 on Windows. I have a problem with exporting the xvi-files. In the documentation it's written that you can have maps consisting of surveys. And so I did. I built a map with projection plan containing just surveys (some surveylines). In the config-file I selected this map and exportet a xvi-file. But the output of the xvi-file contains all survey lines and not just the few inserted into the selected map. (If I select these lines in the config file instead of the map it's working as expected and the xvi-file contains just selected lines) So what's wrong, is it a bug? Second question: I do have some splay stations within some surveylines. Is it possible to export a xvi-file without this splay stations? (e.g. I'm using splay stations for resurveyed points an I do not want to have these in the xvi-files but want to have them in the survey-files.) Third question: Is it possible to plot left and right information to the output if I select surveylines for pdf output? I want to have a pdf file like the xvi-file. This may help for sketching the cave as you can print it on paper and use it as a template. Thanks for your help. cheers, Torsten
