I am still somewhat stuck on this. I have defined a face (3-d area)
and it seems that very few of the vector functions can do anything
with a face like that.
Any other suggestions for doing these types of calculation?
Thanks,

would convert the vector to rasters (2d or 3d) and then use map

Is it possible to use grass to calculate the volume of a part of a
3-D
vector object?
What I mean is if I have a mountain, for example, that is defines
in one
vector map. Then, in another map, I define an area (a plane for
example).
This represents a slice through the mountain.
Is it possible to calculate the volume of the mountain that lies
above the
second plane? (how much rock is above the slice through it?) It
seems like
it should be doable, but I am not really sure how to get going.
Any suggestions?
Thanks,
