Thanks Stacho
This is a useful post, and (assuming it is
correct) deserves to be written up clearly in the Therion Book and wiki.
It potentially clears up problems for
which I (and others on the forum) have been searching for a solution for years.
I may now revisit some of those old
projects when I have time…

stations
As Marco already mentioned, it can be done after playing a
little bit with symbol show/hide.
Well, I needed to run therion in
debugger to see, what is going on.
The problem is, that there are
multiple "attributes" and therion does support only hide show for
single symbol type. Therefore, specification is tricky. But in your case, this
is what you can use:
symbol-hide group centerline
symbol-show point cave-station symbol-show point station:painted symbol-show
point station:fixed
First line hides all centerline
symbols from everywhere (stations and shots).
Second tells therion, that you want
to show stations in the cave. But in fact - point cave-station itself does not
show any symbol. It only specifies, that stations in the cave should be shown.
Therefore 3. and 4. lines are needed
to specify, that you want painted and fixed stations to be shown.
In fact, if you use symbol-hide group
centerline, and want to show some station afterwards, you need to specify explicitely
both, whether you want to show stations in cave or on surface and which kind of
stations you want to show. You can use also symbol-show point station to show
all kinds of stations.
And now I am not sure, whether I
understand my self ;)
But at least, this configuration
seems to work on my data sample.
It would be great to have some kind
of query language, show/hide/color symbols...
