can one edit a drill plan in certain areas not necessarily editing the whole plan but certain parts off the plan without changing already produced information.?
If you let me know what properties of the drill plan you want to edit independently, I can get you a better answer. Thanks.
You can select the drill holes themselves and change the selected drill hole properties. Each drill hole once created has a set of properties and the common ones like Inclination Angle, Orientation, Over Drill Depth, Drill Hole Length, Drill Hole size etc. can be modified individually or as a group.
