Hi all, Feeling like a beginner here with a very simple question, but oh well... "-outline out" is for outer walls "-outline in" is for pillars in the middle of a passage When a wall line is drawn in the wrong direction, you hit "reverse" to make the little tick point inwards. Easy. Until you hit this wording in the old tutorials: "The "outline" option specifies on which side of a line there is the rock." With a *pit* line that is being drawn with its tines facing outwards - as in, the scrap ends at the top of a pitch - the little tick also points outwards, in the opposite direction to most wall lines. ____________________ |- Scrap to pitch head |- A different scrap starts below the pitch ____________________|- Therion doesn't seem to care whether you set "-outline" for that pit to "out" or "in", the result is the same in most cases when creating PDF. Except when creating a .lox file, where it will complain about the scrap outline being invalid if you use "in". So what is the correct value for -outline on a pit with the tines pointing out, when the scrap outline should be the pit's line? And if it is "-outline out", then why do we always draw walls with the tick pointing inwards - surely if it is valid for a pit line to have the tick pointing out and "-outline out", then it is also valid for wall lines to be drawn that way too, so why don't we?
