Command Overview

When moving blast holes, this command controls whether they are maintained on the original plane.

If turned on the when blast holes are moved using the move-blasthole or move-blasthole-row commands the the original plane is maintained.

For example, suppose you have a set of holes with collar locations at an elevation of 10 and this command is ON. If you are in a plan view and you move a hole, the collar location is maintained at an elevation of 10 regardless of the elevation of the current view plane.
