OK- at this point if I select the area then 3 of the lines surrounding the area are highlighted, but not the others? Why is this? Is it a clue to the problem or is the area highlighting just broken? Being able to click on the lines in the area control and have them highlighted would make it much quicker to check an area. (at the oment you have to search for their names, and after the first 3 you need to keep scrolling the preview window). Someone add this to the wishlist :-) >> I >> looked to Command preview window to see the definition and tried to locate >> all area border lines in the scrap.

OK - fixed :-) BTW when I view therion-produced pdf files in xpdf I get this a lot: Error (181503): Name token too long Error (181523): Dictionary key must be a name object The rendering looks OK so far as I can see, but maybe some element is missing. Is this an xpdf problem or something that should be fixed in therion? Do you need an example file?

OK thanx - I don't think I'd have worked that out myself in a month! So I've fixed all that and added some joins between the segments, and that all works reasonably well, but I have a few small problems remaining: Line 81 in soundriver.th2 is a pillar, but I can't get it to be empty. There is an 'outline crosses itself' error in soundriver_pooh which I thought might be affecting it, but removing that scrap makes no difference, and neither does reversing the line. Why is this pillar broken? Also there are a couple of places where there are 'gaps' in the grey background. The most obvious example is the large chamber in the middle is soundriver2_s2 (with lots of boulders). The main chamber has a RH wall which is in the 'middle' of 3 walls. The rightmost wall is the RH wall of a lower passage, formed by the large pile of rocks in the middle separating the upper and lower parts for 30m or so. What is the 'therion way' to draw something like this? Just use a border for the central line? Or split the lower portion into a very small scrap, I suppose? And there is a similar problem on the other side of the chamber (where a steep ramp goes up on the left) BTW - I hope you looked at the scale bar and were impressed with the size of the passage we found :-) All that was found on two pretty amazing trips!
