OK. Done that and if I get rid of all the scraps then I get an image which has complete lines for the surface surveys but station-marks for the underground stations. Is that expected? See http://wookware.org/centrelineonly.pdf However when I put the scraps back in then I only see station inside scraps,not any stations or lines on centrelines which don't have correspondging scraps. Any idea why? I'd really like to get this owrking as it's the easiest way to see which bits I haven't done yet. I have noticed a problem with the need for a 'dummy' survey outside a .3d file import - it stops you using the suggested index.th and index.th2 files for centreline and scrap info (because you need a 'survey dummy' in both files around everything and it complains about 'duplicate survey'). This will go away when we get rid of the need for the dummy survey (maybe you already did that - I can't find the mail right now (I'm using the 20050209 snapshot)). I've also realsied that I can't do what I wanted to do - import more than one .3d file. I wanted to import one per cave, but of course thinking about it, this isn't going to work because the co-ordinates will overlap. I need to generate one .3d file covering al the caves. (no problem except for the need to strip extra hierarchy layers. I wonder if this is going to cuase problems when I want to be able to produce both one large overview survey and various small single-cave surveys. I need to think about this... Still it would be good if it gave a useful error - it took me some time to work out what the problem was as it just gave a tex overflow error - which I can't reproduce right now due to getting a different error: It says: therion: error -- file import -- index.th [15] -- invalid survey name -- de0/.deception I think it is faiing to cope with the oddly-name "de0/" survey. It has this peculiar name because the data is imported from compass and it was expedient to use this name. Survex eats it happily and so does aven so therion should. As ever current dataset here: http://wookware.org/terikan20050217.tgz you need to change index.th at top level to use terikan/terikan.3d and deception/deception.3d to illustrate the above points (I changed it to a single overall dataset to check it worked - it does - very cool - except that I can't get centrelines to appear - indeed it doesn't seem to mattermuch what I put in the various 'map' options I seem to get 'all scraps mentioned in any map but no centrelines' whatever I do?).
