Rename All Holes By Object
This option utilises a design object to indicate the order in which holes of the blast are to be renamed.
A blast must be loaded to run this option. You will be prompted to select the blast and the hole naming options are displayed for modification, if required. You must also select a design object which will control the continuous naming sequence of the holes in the selected blast.

On the Drill and Blast menu, point to Edit, and then click Rename All Holes By Object to display the Select Blast to Rename by Object prompt.
