Those of you with technical questions about 3D surveying software could do considerably worse than contact Wookey at [log in to unmask] Wookey authored Survex and is fairly familiar with the various pros and cons of the other commonly available packages. He is always interested in the peculiar problems of plotting/surveying different types of system (presumably mine surveys will differ considerably from cave surveys). He is also pretty generous with his time for explaining this sort of thing.
