Generate Cones

To access this screen:

In the Command toolbar, run the cone-from-drillhole, or cone-from-string command.
Sample Analysis ribbon >> Plan >> Cones.
Sample Analysis ribbon >> Plan >> Cones from Strings.

Generate wireframe cones from selected drillhole or string data. This allows you to visualize potential maximum deviation per unit length to avoid potential drilling pitfalls.

Note: You can also plan drill and lift deviations using the Drillhole Planner, although sometimes it is useful to visualize the full cone to predict outcomes more clearly.

Activity steps:

Load string or drillhole data and display it in any 3D window.
Run the appropriate cone generation command.

The Generate Cones screen displays.
Enter the Deviation Per Unit Length – This is the maximum expected deviation per unit length of drilling. For example "0.1" could represent 10cm deviation per meter of drilling. If you specify a Deviation Field (see below) this becomes the default deviation value in absence of deviation records downhole.
Deviation Field – If you data object contains a numeric field with deviation data, use this to determine the deviation downhole in precedence to a fixed Deviation Per Unit Length (using that in the absence of record data).
Start Radius – By default, deviation is zero at the collar position of the hole, but you can change this by specifying a non-zero positive value. This can be useful if the collar table coordinates aren't 100% reliable.
Enter a Minimum Segment Length – The smallest segment length for which new triangles are generated in the wireframe cone (default '0'). If a drillhole file contains small sample lengths, specifying a minimum segment length will prevent the creation of wireframes with a very large numbers of triangles.
Optional, specify a Name Field in the drillhole (existing) that is copied to the output wireframe cone. For example, a borehole identifier to ensure wireframe cones and originating drillholes can be associated.
