The Drillhole Planning tool can be used to create (or modify existing) proposed drillholes on maps or scenes; these drillholes are stored separately from the imported data and can be independently exported and shared.
The Drillhole Planning tool has two tabs:
Create - allows you to create a new proposed drillhole by defining the collar and target locations or by specifying the collar and trace parameters.
Modify - allows you to adjust the position of a previously created planned drillhole and save the changes.
