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?
Second answer is NO :) Obviosly, there is another bug. I will try to fix it soon.
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').
If previous bug will be fixed - no problem to remove need for dummy survey :)
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.
May be - I can add some -shift option for import command. E.g. -shift 1200 1300 500 m will shift all stations with given vector. This is no problem and it can be probably very usefull in some cases.
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:
I am curious to see this error - on my computer your data worked without errors.
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.
