Hallo Naomi If you have defined a map with both of the scraps try to change the order of the scraps in the map definition. Best, Torsten

Hi,

I am new therion user - hello everybody :-)

I have a "bad scrap overlay" problem in a cave passage.

The setting is very simple: two galleries (one scrap for each), with a junction at the ceilling. The lox file shows everything ok However, my plan pdf map shows the bottom gallery at the top (should be the opposite !). The problem remains with and without joining the scraps. I can't figure why.

Could anybody help ? Have you got an idea of the possible reasons for bad scrap overlay ?

thanks in advance

Imagine two sloppy passages like faults side by side. On map, one of them should be drawn „above“ another one „bellow“. But there could be a problem for Therion - centerline in passage „above“ is on floor of it and centerline in passage „bellow“ is near ceiling. It means centerline of „bellow“ passage is higher than centerline of „above“ passage. So only human may decide what is „above“ and what is „bellow“. m.s.
