This code is even friendlier - thanks. It does need the symbol-set command as you mentioned. This works : layout test500 scale 1 500 symbol-set UIS endlayout It shows the centerline even without the explicit symbol-show which would lead one to conclude that there is a default symbol-show but not a default symbol-set ?

Is that true? It is not specified in the Therion book... Anyway, I would use the "symbol-hide" and "symbol-show" commands (book p 42) inside the layout section, rather than adding meta-post code. Note that the representation depends on the symbol-set you are using
layout blabla ... symbol-show line survey symbol-show point station endlayout
Eric.
You have to add some layout information. See attached thconfig file (this should also be somewhere in the therion-wiki).
