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
