If you open (Ctrl+O) one file, then import (Ctrl+I) the remaining files, that will get them all in Loch at the same time. Only requires that the same coordinate system is used to generate all files. Is that what you are after? I notice drag and drop works fine to open files, but I could not use that to import files. I'd like to request the option to use Ctrl+drag or shift+drag to import files, if anyone is ever tinkering with Loch.

Hello, i have a bunch of Lox files here, that i want to combine with surface data. I also want to combine all this into one new lox to investigate the caves relationships. Is there any possibility to do that without the source therion data, similar to the survey use method for survex 3D files? Thank you very much! _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
