Drillhole Selection

Drillholes can either be limited by name or by position. If none of the options in this section are selected, then all available drillholes will be used. Entries in the nominated drillhole selection files (.sel), as well as the drop-down lists, may contain wildcards (both * multiple and ? single character).

Tip

You can create a drillhole selection file by selecting drillholes of interest, then right-click and select Drillhole > Selection File from the context menu to enter a file name and save the .sel file for future use. This essentially creates a text file that contains a list of hole identifiers with the format shown below. You can also create a selection file manually using a text editor and saving the file with the .sel extension. Note that drillhole names in the selection file are case sensitive.

Drillhole selection file format:

DD00026
DD00035
DD00044
DD00053
DD00116
DD00143

The following selection methods may be used in combination.
