Define Grade Parameters

Function

This command creates the attribute file for the block model. It contains the attributes, grade names, prices and the ranges. The Name of the grade may appear on the list more than once, if several options exist to create a certain grade.

Choosing Add or Edit brings up the Edit Grade Parameters screen for up to 8 parameters at once to define a grade and color. There are four Operators: <, >, =, and Not =.

The Draw Legend button places a legend in the drawing as shown here where the grade name is displayed next to the color sample in the legend. The user chooses the legend layer and size. This is useful after color hatching a fence diagram. Drawing the legend next to the fence diagram is a good reference to see the quality of the ore.
