Bruce,
thank you very much for that fast answer! But..
That idea is good for making the data of the centerline and the
wall-points easier to handle. So far I will do it in that way you give
in example one in future. That is the way we survey a cave normaly.
Earlier with this data we have drawn the map after it was estimated with
CaveRender. So we have got the dimensions. Additionally we have made a
coorekt scaled drawing in the cave. Today with Therion, if the drawing
in the cave is correctly (or nearly) scaled that way is not longer
necessary. But it is a good tradition and a possibility to proof the
drawing of the map.
In this relation my original question was: What must I do (and now I try
my question in an other way), if I namely want to have all data in my
data-file, but in the Map there should shown only the
main-station-points (1, 2, ...)with name along the centerline. The
Station with extention a, b, c... should not drawn and named.
May it be, that that is only possible with a different METAPOST-Code or
is there a possibility in Therion itself?
In both cases of your example I get all stations drawn and named.

I have never used splay survey legs, so perhaps I am not the best person
to attempt an answer to your question, but I think it is what you are
after.
Look up 'flags' on page 19 of the Therion Book for a description. I'm
guessing you would have to modify your data entry as follows...
data normal from to length compass clino left right up down
1 2 10.83 125 -12 3.5 1.0 0.8 2.0
flags splay
1 1a 1.0 125 -12 3.5 1.0 0.8 2.0
1 1b 2.0 125 -12 3.0 0.8 1.2 1.5
1 1c 3.0 125 -12 2.5 1.0 2.0 1.5
1 1d 4.0 125 -12 2.0 1.5 2.0 1.0
1 1e 5.0 125 -12 2.2 1.0 2.0 0.8
1 1f 6.0 125 -12...
flags not splay
2 3 ...
My personal preference is to separate the survey leg data from the
dimensions data as follows;
data normal from to length compass clino
1 2 10.83 125 -12
etc
data dimensions station left right up down
1 3.5 1.0 0.8 2.0
2 etc
I find it easier to check as there are fewer numbers in each row, and it
is explicitly stated which station the dimensions apply to, but there
are very many ways to do it depending on your preference.
