Compliance Areas from Grids

This command draws a closed polyline(s) and hatches the area(s) that meet the specified values for multiple grids. It is similar to the Parameter Compliance from Drillholes, but this analyzes grid files instead of drillholes.

The Set Parameters window is for selecting the grid files and specifying the values to use for compliance. The bottom portion is for choosing the layer, color, pattern and scale for the hatch. The area(s) that meet the criteria are then outlined and filled with the hatch pattern. If no inclusion/exclusion perimeter is selected, then the area of the extrapolated grid is hatched to the limits. As can be verified by the prompts, the command contours each of the grids for the values specified and then creates closed polygons where the values coincide.
