I agree that in the cave would nobody calls the massif between two passages 'pillar', but therion sees things purely geometrically -- doesn't matter if a closed loop within a passage is small or large, formed by a fallen block or two passages. So everything surrounded by a scrap border and not belonging to the scrap is a 'pillar' and need to have "-outline in" option specified. >> OK. so there is some threshold of closeness that prevents a join happening >> automatically (to the right place).

Yes, there should be a warning that therion couldn't find a join. >> Also what happens if an area crosses a scrap join?

It would work, but areas (the pattern) wouldn't join smoothly :(( There is unfortunately no better solution now. Martin
