Interesting. The fact that red and green are not consecutive should not make a difference. I don’t remember seeing this before. As Martin suggests, it may be an issue with your particular viewer, try some other viewers to check this. Or maybe it is an issue with ‘break’ as Torsten suggests, although that would normally manifest with equal width and full density lines. Torsten’s suggestion hinting at other line types over the green walls deserves a look, but if that were the case, I would expect they would be grey also – as in the water in the red scrap near the word chem17. I notice the word P5 presumably part of the green scrap renders correctly. Are all your scrap lines actually associated with the scrap that you think they are? No unintentional doubled up lines?

I drew a plan to explain that: <file://Users/martinkern/Library/Containers/it.bloop.airmail2/Data/Capture%20d’écran%202018-10-20%20à%2015.43.33_1_2_preview.jpg> On my survey, the blue scrap is the n°1 and it is above the red (the second). Here the overlaying is good. The red scrap (n°2) is above the green (n°4). So, there is a scrap n°3 between the red (n°2 and the green (n°4). (It does not appear on my plan.) My problem is that the overlaying of the red scrap over the green is not "normal". The lines are thinner. Why that? Because these two scraps are not consecutive? I would like that they are as the other overlaid lines. It’s possible? All these scraps are contained in the same map. Thanks, Martin
