Hole 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

Selection Files

Use selection files (. sel) to include or exclude a large number of drillholes.

Selection Names

To include or exclude three or fewer drillholes, enter collar names directly in the Selection Names area. Entries are saved in the FixDHD specification file for use in later runs.

Drillhole names entered in the pane are case-sensitive.

Select by Polygon

Select by polygon spatially includes include drillhole collars which fall inside a defined polygon.

Design database

Specify the design database that contains the layer and polygon object. The drop-down list contains all design database files found in your current working directory. Click Browse to select a file from another location.

Layer name

Specify the name of the layer that contains the polygon object. The drop-down list will contain all layers found in the chosen design database.

Object name

Enter the name of the polygon object that will be used to limit the drillholes. Wildcards (both * multiple and ? single character) can be used.
