Check if there is not a double station in a scrap - squezed pillar. Martin Odesláno z iPhonu

I gave this a try ... I drew partial pillars on the edge of each scrap using a normal wall line. I changed the straight lines between the pillars to -visibility off, and I added a "join scrap1 scrap2 -count 2" to the .th file. The result is not quite as badly mangled, but it is still not right.
Taking out the join statement gives a map that makes more sense. There are still some artifacts where the two scraps join, and the walls on the pillar between those two scraps don't line up quite right.
I also tried it using "join scrap1 scrap2" and no -count option. That produced a reasonable map. The wall on the east side now has a smooth join. The pillar in the middle still has discontinuities.
I checked the "reverse" box on the pillars which are completely contained in a scrap. It made no difference I can see. When I drew those lines, I went in a counter-clockwise direction.
On the upper scrap I drew lines between the pillars. I did not draw those same lines on the lower scrap. Is that needed?
One thing that is very apparent here is that the in-cave survey and sketching will have to be done exactly right.
Two attached PDF files, one with the "join count 2" statement and the other with no join statement.

If I draw only that part of the column which is in each scrap, can I still use "-outline in"? No, those remain -outline out. Also your sketches for surveys should not include the parts of the pillar walls that have not been surveyed! Will I need to use line joins to get the two parts of the column to come together? No, use join scrap1 scrap2 -count 2 And you will need to replace line wall -subtype invisible with line wall -visibility off as is intimated in https://therion.speleo.sk/wiki/drawingchecklist#wall And will that result in a column that is entirely white on the inside? Yes, but only once you have all wall lines in place and parameters for all lines correct (-reverse, -outline, -subtype, -visibility) Bruce
