Re: [Therion] WG: Therion crashes in shapes.h when generating 3D
Michael, The th file with centerline is not centerline you used when sketching in PocketTopo. So there is not possible to assign stations from your sketch to stations in your centerline. Correct way could be to connect both centerlines in another th file one level higher and command "equate" equate SA09@old_survey 1.0@new_survey A scrap is a continuous small piece of cave. To define discontinuous scrap with holes is not the best idea. I attached your th2 file divided to 8 scraps, but there are not stations defined in centerline so the map is not possible to export. Any scrap must be calibrated (georeferenced) either by at least two stations or scaled in scrap section. The section was not scaled, so I did it too. It is good idea to add all stations belonging to a scrap to that scrap first. You may use "Convert to curve" command in Line section to smooth your walls and other lines. In your scrap there are several empty lines and lines with only one point. Delete them.

Only happens when generating 3D of any format. Producing plans (pdf, kml) works. I'm running Therion 5.4.1 on Windows 7. The crash seems unrelated to the last scrap processed before the crash, because when I exclude that scrap, it crashes after approx. the same time with a different one. Any help appreciated, Michael. <Therion-Crash.jpg> _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
Hello Martin, Thank you so much for taking the time to analyse the scrap and your improvements! With your hints I was now able to turn it into something digestable for Therion. If you still want the testcase with complete TH-File for code debugging, let me know I’ll then send it to you directly. Cheers, Michael.
