Sorry for late answer.
Actually, we use such data drawing xelevations. Its useful to draw a
small plan of a vertical passage close to the same place in a
xelevaton. It would be nice to have such function in therion though
it's not highly important. I attach an example of a simple cave
An other thing - we have already done several surveys of some caves
the way I mentioned. So it would be good to enter the data to some
software the same way.
