[Therion] Therion Map Header Overrides

[Nick Bairstow]

Bruce, I have never used flags. I have just been though the Therion book and wiki for information but for clarification could you post an example of surface flag use please.

Thanks.

Nick

I'm not sure that is a very good way to deal with the issue.
In the screenshot below I have a surface survey shown (green dots), designated surface by use of 'flags surface', 'flags not surface' interleaved with the survey data as appropriate.  No need to fudge the cave length or depth because Therion does not include surface data in the cave length.
There is some complexity around it, but you can show or hide the cave and surface centrelines using;
  symbol-show group surface-centreline
  symbol-hide group cave-centreline
