Hi Maciej and list,
thanks for your reply, I will try to get some more info about tangential

By the way, does anyone know if GEOLOGICAL SURFACES like fault planes or
bedding planes (not "phenomena", like gas emissions, etc.) can be modeled with
v.surf.rst? or with some other grass-command? Has anyone done it?
