This command highlights drillholes that contain a strata that
meets the specified parameters. The drillholes are highlighted by
drawing a circle around them, changing the drillhole symbol,
changing the drillhole type or changing the drillhole layer. There
is also an option to create a selection set of the matching
drillholes. Then you can use that selection set in any other
command that prompts for drillholes by entering P for Previous at
the Select Objects: prompt.
The parameters are set in the Define Parameters window. Be sure to spell the attributes exactly the same in the parameter list as in the drillholes. For more details about parameter definitions, see the Define Parameters command.

option composites the strata using their bed names into BED_TOP,
BED_PARTING, BED_KEY and BED_BOTTOM. For example, you could have
several quality samples of a seam broken into strata names CO with

samples into A_KEY. Otherwise the parameter filter will test each
sample separately.
