[Therion] Incorrectly Drawn Scraps

[Carl Magnuson]

I have been working on a larger cave and storing all the survey data  
in my own program which exports to therion files.  For a particular  
survey the scraps are not being drawn correctly, but drawing just the  
centerline from the survey data looks fine.

Posted here http://mbug.dyndns.org/example/ are two thconfig files,  
one with the scraps and one without and the generated PDF files.  The  
shot B009-B010 for example looks fine in the just centerline export,  
but does not show up on the export from scraps (even though it has a  
scrap which looks correct).

Does anybody know why this would be happening?  I do not see any  
errors from therion, even running it with the -d flag, and it appears  
to me that all the input data is formatted correctly.

Thanks,

Carl
