[Therion] Export centerline and/or stations to SHP without th2 files

[עמרי גסטר]

Thanks,
I know cave view, it is very useful.
I noticed that if you press with the mouse on any location it gives you the
hight from surface.
There is a shading called  depth below surface, but it stops at 23m (by the
way is this a bug?), I know that there there are places with far greater
depth then 23m.
I'm attaching a screenshot with the problem.
