Command Overview

This command lays out a blast pattern presplit line using a blast patterns file.

It is strongly advised that you add the attributes BENCH and BLAST. These attributes are required to use the move-blasthole-row and move-blasthole commands. Attributes can be added using the add-attributes command. The drillholes created will have the attribute values of the outline perimeter.

You are first asked to select a perimeter which defines the outline of the blast. You then define the line of the presplit. Snapping is permitted.

If a blast patterns file patterns file is not open you are asked to select one.

You are then asked to select a pattern number from the patterns file and a prefix to be used for the holes created within this pattern.
