SexyTopo is a tool for assisting in cave surveying. It interfaces with an automated measuring device (the Disto-X) and builds up an accurate model of the cave. It also provides a sketching environment for the cave surveyor to fill out the details.
SexyTopo is still BETA SOFTWARE. It is under active development and may have a few missing features or bugs. There is no guarantee that it will not lose all your data. If you have any problems, please send me a bug report (Google "sexytopo" for the github page). Please also submit any error reports that may be generated.
