Hi! I'm a beginner in Therion so please be patient :) I'm drawing a fictious cave in order to learn how Therion works. So far I have managed to join two scraps from one .th2 file and surveydata from two .th files. The pdf-output didn't look too great however, since an underlaying passage isn't hidden when it crosses the upper passage. I figure this perhaps depends on that there was no station points in the scraps? But when I create station-points in my scraps (I have a xvi background so the station names are created automaticly) I can not compile anymore. I get an error: *********** D:\Therion\therion.exe: error -- karta1.th2 [11] -- station does not exist -- 3 ************ Pointing to this line in my th2 file: ************* point 150.385 330.105 station -name 3 ************** What am I missing here?
