HI Everyone,

A friend messaged me while I was lucky enough to escape the UK and get to spain for some caving, which was great!

I've got back and tonight I tried to look at the problem he was having outputting in Therion 6.0.1

I ran his survey in 5.5.3 with no issues whatsoever, I thought he could be getting a bug from 6.0.1 so i updated my software, and now i'm bugged in 6.0.2 with the metapost exit code on his survey.

Since I don't take logs of non-positive numbers,
I'm zeroing this one. Proceed, with fingers crossed.

C:\Program Files (x86)\Therion\therion.exe: error -- metapost exit code -- 2
writing xtherion file ... done

I don't know whether its a bug or whether there is an error with the config file which only presents in 6.0.1/2

but I thought I would send it to the list for thoughts?

Alastair.

please find below config file which ran fine in 5.5.3
