questions on therion

[Wolfgang Zillig]

Thanks a lot!

That was it! I'm quite new to therion but the reason is quite obvious. 
But there is another problem with symbol scaling (station marks)

Hm, I tested it again today and it works now even without grid. Strange, 
I don't know what I did yesterday. It also seems that Therion crops the 
image to the layout size. Is there a way to get the whole image with the 
centrelines (or outlines,..) but with no additional north arrow or other 
layout stuff?

This works but it changes the symbol sizes of the stations also. I've 
added two pdfs which show the different scales. I only have the 
centreline data (and stationmarks) visible with some metapost code. The 
best would be to swich station marks off. Here the  layout part of my 
config:

layout test
 #scale 1 20000
  scale 1 1000
     surface bottom
 
  code metapost
  def l_survey_cave (expr p) = draw p withpen PenD withcolor (0.1,0.3,0.1);
  enddef;
endlayout

Thanks

Wolfgang
