Thanks Ben Appreciate the explanation. The way I have been working is pretty much the same as what you describe, and apart from some confusion over the difference between 'input' and 'source' commands, and LRUD data, it's been fairly straight forward and successful. Ladislav's reminder is helpful. On reading the Therion Book I am not clear on which station the LRUP data is supposed to apply to if only one set of the number pair is provided? Anyway Ben. Your explanation stops short of the point where my difficulty begins. So once the scraps are produced, I'd like them to turn up in the output files, pdfs, for example, so that our centreline plots become cartographed maps as we progress through the drawing process. I am sure there is a simple misunderstanding I have that is tripping me up. There seems to be quite a good explanation at http://therion.speleo.sk/wiki/doku.php?id=tbe:wiki3 but Therion keeps coming up with errors. Maybe I should try replicating exactly the example from the Wiki, or spend some more time with the 'rabbit cave' example that comes with Therion... Bruce
