Related to the issue of the inclusion or
exclusion of particular station symbols in pdf outputs, there is a long
standing behaviour that has been frustrating me.
I would like to create a pdf that has;
-cave passage outlines, but no cave survey
network information, and
-fixed surface points with labels, and no
surface drawings and no other surface survey network information.
I have used these statements in a layout;
symbol-hide group all
symbol-show point station
symbol-hide group
cave-centreline
symbol-hide point
cave-station
symbol-show group
surface-centreline
symbol-show point surface-station
symbol-show point flag:entrance
symbol-show point
flag:sink
symbol-show point
flag:spring
symbol-show point flag:doline
symbol-show point flag:dig
symbol-show point
flag:continuation
They more or less describe what I want
(except for the surface centerline statement).
I have used two source files.
‘One’ references cave data
that has lots of drawings, plus a small amount of surface data and surface
drawing.
‘Two’ references surface data (and
a few cave stations) that is almost exclusively made up of fixed points (gps
data) and has no drawings.
If I reference ‘one’ only then
I get the following image. Pretty much what I wanted, except for the
surface survey stations (notice that I have ‘symbol-show group
surface-centreline’ above, but the surface centerline is not plotted).
If I reference ‘two’, then I
also get pretty much what I want, except that some of the points that are
displayed are cave-stations.
The above two screenshots from pdfs are created
with the same dataset and cover approximately the same area and are at
approximately the same scale.
So, apart from the minor exceptions
mentioned, I would like to create a pdf map that is a superposition of the two screenshots.
When I reference both sources ‘one’
and ‘two’, in the same thconfig file, the project compiles and
outputs are produced. The problem is that the pdf output produced looks
identical to ‘one’ above. Ie the source that includes mainly
surface data is not included in the pdf.
For this example other types of output such
as .lox and .3d are created correctly.
Would this be a bug? Or something I am
doing wrong?

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...
