</head><body><p>Hi Martin<br></p><p>Thanks a lot for your hints. Espacially the infer command (I didn't know this).<br></p><p>While playing around with this command I recognized no change in behaviour to vertical shots.<br>Of course this could not be and something else was wrong.<br>In the end I realized that all lines in the Therion .ini file where with comments.<br>Of course therefore it didn't make any difference in changing loop closure method from survex to therion and vice versa.<br></p><p>I'm using a windows with Therion and if you have a look to the ini file there are missing all line feeds.<br>Therefore this ini-file is not that readable... anyhow. I build this file new with command "therion.exe --print-init-file" and all line feeds where in place.<br>Than I realized my mistake and uncomment the line with loop closure method.<br></p><p>And now I have to say: there IS a difference in the effects using loop closure method survex or therion.<br>With 'survex' you get the problems I observed (0m beeing not at the same level and other misplacements).<br>But with 'therion' as the loop closure method it worked very good and I got all 0m lines at the same level. But some minor misplacements nevertheless.<br>And with the command 'infer plumbs on' it looks pretty perfect.<br>Vertical shots stay vertical and after loop closures as well.<br></p><p>Hopefully my problems with the elevation view are solved now...<br>I have to check some more details but it's looking pretty good.<br></p><p>Thanks again for all the help and sorry for my confusion with the loop closure method.<br></p><p>regards,<br>Torsten<br></p><blockquote type="cite">Martin Sluka via Therion <therion@speleo.sk> hat am 3.
