I noticed an export item 'cave-list', however I get empty output files. I can not find much explanation of this (new?) feature. I have three caves with survey data entered, and a number of scraps, and one cave entered as a scan of a plan view of an old cave map (no survey data, but two dummy stations with co-ordinates entered) Two of the surveyed caves are connected by survey centrelines, and one is not (but will be when finished entering data) One of the stations for each cave contains a line similar to; station N2 "Greenlink Entrance" attr entrance and my thconfig file both for an individual cave, and for the system of all four caves, contains something like; export cave-list -output ../Outputs/Greenlinkcaves.txt\ -location on Alas I always get empty outputs. What data should be entered to obtain output? What information is output? Thanks Bruce PS I like the new look Therion Book, new behaviour of layout-comment, how Therion now tidies up it's temporary files and the warning highlight in the Compiler with the new 2008.04.16 snapshot. Good work!
