[Therion] Splays appearing when not selected

Tue Feb 2 09:48:53 CET 2021

Hm, that didn't help, unfortunately.
in the meantime I also tried coloring the PDF by altitude, this is not 
affected and working like expected.

Martin has readonly svn access to the data and may investigate in the 
dataset?
I just unlocked it for that purpose.

The affected thconfig is svn/Hirlatzhoehle/Zubringer/therion/thconfig
and the scrap in question is in  
svn/Hirlatzhoehle/Zubringer/1/therion/1.1.plan-2-b.th2
The last known station is 1.2.26j

In the thconfig I noted the following (just local here)

# Hirlatzdaten importieren
source ../../../Hirlatzhoehle/therion/Hirlatzhoehle.th          # wrong 
dimensions in lox
#source ../../../Hirlatzhoehle/Zubringer/therion/Zubringer.th   # works 
somewhat-ok in lox (still extruded to top of box, but the box itself is 
small)

Greetings,
Beni
