Ah yes, doing it as separate scraps is a lot less messy. Though in the end you then probably have to keep using multiple scraps, even if the idea was to warp it into a nice shape so you can draw it up as a single scrap. I tested out the "sketch-warp" option (that goes directly in the .thconfig file, not inside the layout). "plaquette" gave a very good resulting shape for my demo case (and was really fast!), but made the lines jagged and hard to see. "linear" preserved the sketch best but caused more distortion. "point" took forever, but the result was absolutely excellent. It is interesting to me that the default "line" gave the worst result of all options. The Therion book does not mention "linear" or "point", and could do with an update. I found more details on this very old tutorial: http://marcocorvi.altervista.org/caving/tbe/m_04/m_045.htm Torsten, that article is a treasure trove for you! > Note: You may change order of morphed sketches and xvi with splay shots, > centreline and xvi mesh, switch visibility on/off, move them to exact > coordinates in “Background sketches” part of Map editor. Are these documented anywhere? Specifically how to use the options. I can see the "point extra" options in the linked article above, but not how to use the coordinates or visibility. Feeling like I must have missed something, since the Therion book doesn't mention "background sketches" at all, and only describes setting <x> and <y> coordinates for the scrap's -sketch option. I am guessing that x/y lets you offset the sketch to a more useful location relative to your stations (though I have no idea why you would need to). _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
