Hi Peter, you can use v.to.rast to create a raster surface from the vector surface (as Maskus suggested) and then use r.to.rast3elev to fill the upper volume and the lower volume of a new voxel map with different values (upper = 1, lower = 2). Then use r3.mapcalc to perform operations on the upper or lower volume (r3.mapcalc "lower_volume = if(myvolume == 2, 1, null())").
