Select Holes by Collar Table Data

Use the DH-Plot > Select Holes > By Collar Table Data menu option (DHSELCOLLAR GX) to select holes based on values in a channel in the collar table.

Select Hole(s) dialog options

Collar table data	Select from the list any "string" or "integer" type channel found in the collar table. "Float" type channels are not listed, because the behaviour of a string-type comparison on floating point values is unpredictable, due to the number of decimals displayed etc.
Append/New	In "append" mode, holes already selected remain selected. In "new" mode, before any new selection is made, all the holes are un-selected.

Application Notes

Once a data channel is selected, the two-panel selection tool is displayed with all the available items which can be selected. Select one or more, and then all holes with corresponding matching values will be selected.
