This command creates a distance grid file where the value of
each grid corner is set to the distance to the nearest data point
in a drillhole. This is useful to see the distance between
drillholes when planning additional drilling. The grid can be
contoured, as shown below, for better analyzing. The grid
dimensions are set first, then two dialogs appear to select the
strata to grid, and the attribute to grid.
