That is entirely up to where you draw your invisible walls. I would try not to allow them to go through any area fills, but you can join feature lines too, so either clip off, or two separate lines with a join. The reason Therion struggles with your drawing is that your gaps are bigger than the passage width. It needs gaps in the walls to be narrower than the width across a passage. It tries to close gaps with the "nearest end of a wall", which is the far side of the passage, instead of the wide gap. You can leave gaps, just not such wide ones. So if needed, an invisible wall across the mouth of a passage (that is not in the current scrap) might help. > A thought occurred as I was writing this.

A grade 1 helps plan the grade 5+. It is something you can expect to happen. We hit the same issue in one of mine - a collapse chamber with loads of walls that are actually not walls. You don't realise until afterwards. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
