This routine colors the 3D grid faces plotted in the
drawing. It uses the colors defined by layers, or in the strata
definition file
and matches the names up with the intervals in the PreCalc. It is very
useful
for locating the outcrop of strata, or displaying the subcrops of seams
to a
mining bench grid. This colored grid can then be viewed in 3D and
shaded for
full visual effect. Shown below is a final pit of a sand and gravel
quarry. The grid has been colored by the seams defined in the PreCalc
file. There are options to set the subdivision tolerance. 0 will not
subdivide the grid cells. A max of 5 will subdivide the grid into very
small cells, for example, 50 x 50 grids will subdivide down to 1.5 x
1.5. There is also an option to use the SDF file from Define Strata for
the coloring and layers.
