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 50 parameters at once to define a certain grade and color. There are six Operators: <, >, <=, >=, =, and Not =, combined with either and AND or OR for defining the grades.
The grade Color is used by viewer commands
like Block Model 3D Viewer. The Geologic Column Scaler is
used by Draw Geologic Column when drawing in 3D mode for sizing the
strata column by the grade parameter which is a way to highlight
target grades. The Pass Any Missing Strata Attributes means
that if the strata is missing any attribute in the list, then the
program will count that attribute as good even though it doesn't
have a value. This option applies when a grade has some attributes
to check for but only for when those attributes are available in
the strata.
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.
