I'm new to Therion, but think it is fabulous!  I am just in the process
of drawing up our new discoveries in Mendip, UK, and like Andrew am
looking at how to include the centreline in the map pdf output.  (It is
visible in the model output but not the map).  I have tried including
the "survey" in the list of maps (and additionally found that I need to
specify the -projection plan option).  However, no centre is visible in
the pdf output.  Have I misread your email: is this something the
software should already be able to do, in which case what have I missed
out of my .th file?

... The only way how to do this is to add surveys to the map  
structure.

Example:

You have 3 maps and 1 survey without map. You define

map map_total
   map1
   map2
   map3
   survey_without_map
endmap

I will put this problem into TODO list.
