Description

Layout a blast pattern within a perimeter to create a new set of drillholes

How to Use

1. Run the Command.

2. Select a perimeter which defines the outline of the blast.

3. You then define a base line of the blast. Snapping is permitted.

4. You then need to confirm the X and Y location of the first hole using the Confirm Hole Coordinates dialog.

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

6. 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.

This command lays out a blast pattern within a perimeter 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.
