G'day,

I have a table of records representing a 3D block model of an orebody, such that each block has X, Y, Z and then properties (grades), such as Ni, RecNi, Cu etc, as well as 2 volume fields, MinVol and DilVol. Each block is 20m apart in X, 20m apart in Y and 10m apart in Z.

So 2 adjacent blocks would have coordinates:

X(8510), Y(19500), Z(100)
X(8530), Y(19500), Z(100)

I am...
