I'd need to process a whole survey hierarchy at once to benefit from the loop closing in cavern. Cheers, John

The hardest part of reading the file formats is pinning them down. Larry Fish was very helpful in resolving minor ambiguities in the Compass file format descriptions, which was very useful when writing the Survex support for Compass formats. Without a precise spec or a lot of sample data from a range of sources, you're likely to end up handling just a subset of the format. But generally it's going to be easier for processed data formats than unprocessed data formats as they're written by machines, so the format-as-defined-by-use has a lot less variation, even if you don't have a formal specification. >> So I suggest to add new command: >> >> input-centreline >> >> It will add survey stations and shots from given (.3d, later may be >> compass, toporobot, vtopo etc.) file to current survey.
