Looking at this whole thread to date... I use same version of therion and windows as Andrew, plus Vladimir's beta as well. I have many projects that have multiple entrances defined, as well and main entrances, and in a hierarchical structure. Never any problems encountered over many years, once I understood the, main entrance – minor entrance distinction. Andrew, it is not just that you are using a different computer or editor, and the ‘survey -entrance’ is turning into ‘survey –entrance’ (ie short dash to long dash)? Or some other unexpected thing like that? A sample main entrance definition, a bit complicated, but it works for simple ones as well; survey a -title "Survey A Upper levels to Smaugs Hall towards Connection Pitch Middle Earth Cave" \ -entrance a1 At a higher level index file I name the main cave appropriately, ie survey GLMESM_system -title "Greenlink, Middle Earth,<br>Swiss Maid Cave System" The export statement I use is; export cave-list \ -surveys on \ -location off \ -output ./Output/GLMESM_SystemCaves.html And it produces output like the attached image, which has a 4 level deep hierarchy, main caves entrances, minor entrances and unexplored entrances all included… Bruce -------- Original message -------- From: Andrew Atkinson via Therion <therion@speleo.sk <mailto:therion@speleo.sk> > Date: 10/01/17 00:54 (GMT+12:00) To: List for Therion users <therion@speleo.sk <mailto:therion@speleo.sk> > Cc: Andrew Atkinson <andrew@wotcc.org.uk <mailto:andrew@wotcc.org.uk> > Subject: [Therion] Entrance for cave list Page 17 of the Therion hook states that station <station name> Under the context survey should be used as the entrance identifier for a cave to be used in cave-list export. However, this gives an error unknown command -- entrance Now I can sort of get round it using Station 0 "" entrance in the centerline, but this does not define a cave so the list is a bit weird.
