Build Drillholes Dialog

Defining trace settings when creating dynamic and optional static drillholes

To access this dialog use one of the following:

  • In the Define Hole Tables dialog, click Rebuild....

  • Activate the Sample Analysis ribbon and select Prepare Samples | Rebuild Holes

The Build Drillholes dialog is used to define hole trace settings during the creation (or recreation) of dynamic or static drillholes.

Field Details:

The following options are available for dynamic drillholes:

Create new traces for all holes: if this option is selected, a new trace will be created for every drillhole defined within the supporting tables used to build the drillholes (as specified with the Define Hole Tables dialog). You should select this option if you have:

  • Changed collar or survey table definitions and field assignments.

  • Edited the collars or surveys tables.

  • Imported new collars or surveys table.

Use existing traces and only desurvey new holes: selecting this option will ensure that dynamic drillhole data will only be created for holes that are not currently represented as static (desurveyed) holes, preserving any existing desurvey data. You should select this option if you have:

  • Changed the table definitions and field assignments of assays, lithology and other log tables.

  • Imported new log tables.

Create Static Drillholes: optionally check this box to additionally create static drillholes from the dynamic drillhole tables during the hole building process. If selected, a new static drillholes object is created in the current project, that can be saved to a physical file by saving your project (File | Save). In this situation, drillhole data is not retained in memory at the end of the process. If this option is not selected, dynamic drillhole data will be created in memory.

Add samples for each survey point: for static drillholes, add additional sample intervals at survey points

Remove Dynamic Holes: remove the dynamic drillholes object from memory after the static drillholes object has been created.

When creating Static Drillholes via the Build Holes dialog, a static holes overlay will be added to all views (including Plots window views). For more information on how your application  uses overlays to represent views of objects, see View Hierarchy.
