This command creates contours for the depth between the surface
and strata. The surface models for the ground and strata are
modeled by grid if coming from the screen entities and drillholes.
When using the PreCalculated file, the list of strata appears to
select which strata to use. Specify Depth Contour Range allows for
a starting and ending contour elevation. There is the option to
contour the depth to either the top or the bottom of the strata.
Options are at the bottom for smoothing and reducing the contour
vertices. This is basically the thickness from the topography to
the top or bottom of the strata. This grid could also be made in
Grid File Utilities, but this is a quick way to get the contours
without griding first.
