Hello everyone - I have been working on a multi-cave project for a while. Each cave exists as its own separate set of files. A few months ago - with help from this group - I figured out how to get a single output file that contains all four cave maps. The combined map is generated from a single thconfig file that uses "source" commands to bring in the .th files from each of the member caves. Now we have surveyed a link between two of the four caves. I need to set up an "equate" command so that the two caves actually link up. According to Aven, the gap is about 30 feet. Some of that, I am sure, is due to rounding errors in the GPS locates for the two caves. Based on a message from Martin, I added a .th file which contains a "survey" command. However, that is generating an error from Therion: ========== therion 5.4.1 (2017-04-18) cavern - Survex 1.2.34 initialization file: /etc/therion.ini reading ... done This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdfetex) restricted \write18 enabled. entering extended mode (./fonttest.tex checking optional fonts csr10 csti10 csbx10 csss10 csssi10 ...
