[Therion] Best structure to use for using 3d files.

Yes, you may do it like this (if you need survey structure also in  
therion). If not, just use -surveys ignore when importing 3d data. Or  
you may use -surveys create, if you do not want to add empty containers.

Use -layout-survey-level all when exporting map. I am sorry, it is not  
documented in therion book. We will add it.

If you have no map or scrap, then stations will be exported  
automatically. Otherwise you have to insert survey into map and  
display this map.

You have to redefine line symbol in layout

layout centerlines
code metapost
def l_survey_cave (expr P) =
   T:=identity;
   pickup PenC;
   thdraw P;
enddef;
endcode
endlayout

and use this layout in export

export map -layout centerlines

This question is definitely for people using survex + therion. I have no idea.
