[Vasily Vl. Suhachev]

Hello

How to show entrances on map?

If I create a model the entrances is displayed. But how to display them 
on the map?

My thconfig follows such shema:
===
source

   centerline
     cs lat-long

     station ent1 "Entrance 1" entrance
     fix ent1 ...

     station ent2 "Entrance 2" entrance
     fix ent2 ...
   endcenterline

   surface
     bitmap ...
   endsurface

endsource

export map -o surface.pdf
===

PS:

And addition question: what is purpose of 'mark fixed' command?
