svx files with unconnected parts

[Duncan Collis]

Occasionally we end up with a .svx file containing bits of survey which are not connected directly to each other. Currently to print these out it's necessary to selectively comment out parts of the file and reprocess.

Would it be possible to add the following behaviour to cavern?: on processing a .svx file which contains parts that aren't connected to each other, optionally (dependent on a command line option) produce multiple .3d files, one for each part of the survey. So for example foo.svx containing 3 bits of survey that don't connect directly to each other would result in foo.part1.3d, foo.part2.3d foo.part3.3d

Generating multiple .3d files is awkward to do, but Survex 1.4.10 will change the handling of this case - instead of an error for unconnected bits of survey, cavern will issue a warning and then ignore the unconnected bits of survey.

Hopefully this addresses the stated problem adequately - you no longer need to selectively comment out parts of the file and reprocess to print it (and then remember to remove the commenting out again).
