Thank you! This seems to have sealed the idea in my head. It's a convention because it matters with some ornamentations. And it almost always makes sense because the tick points towards "air". Except when it's a boulder. ;) > As you have picked, the pdf engine can solve the problem of what is the > inside of a passage Since the line's orientation has little/no effect on where the engine chooses to decide is the "inside" of a structure, this makes me wonder ... Maybe there is a possibility that I can construct a cave where the proximity of openings/entrances and passage curves will cause it to construct the passage on the wrong side of a line. And in such a case, the solution would be to make invisible walls. Interesting. I will probably randomly bump into that, one day. Anyway, thanks for explaining it to me. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
