cone-from-string ("cnfs")

See this command in the command table.

To access this command:

Sample Analysis ribbon >> Edit Drillholes >> Cones >> Cones from String.
Using the command line, enter "cone-from-string"
Use the quick key combination "cnfs".
Display the Find Command screen, locate cone-from-string and click Run.

Command Overview

Generate a wireframe cone from a string. Typically, this cone is used to assess the impact of production deviation from a plan, such as a planned drillhole direction or drive development. This can be useful to assess the potential proximity of development or drilling in relation to other important and known structural milestones such as a stope cavity or other developments.

Command steps:

In the Current Objects toolbar, create a new wireframe object. See Current Objects Toolbar.
Run the command.
In any 3D window, select a string.
Using the Generate Cones screen, define the following parameters:
- Deviation Per Unit Length — enter the maximum expected drillhole deviation from plan here. Bigger values create shallower cones (with a greater potential deviation and an increased risk of proximity detection warnings.
- Deviation Field — an optional field in the drillhole object that denotes the deviation from plan (potentially per sample).
- Start Radius — the deviation from plan at the start of the hole. This can be regarded as the upper cone radius.
- Minimum Segment Length. — the minimum possible length of a cone segment from its neighbour. The average sample length is a reasonable guide for this.
- Name Field — if specified, this value is added to all wireframe cone segments.
Click OK.

A wireframe cone is created based on the above parameters, starting at the initial string vertex and deviating outwards along the length of the string.

The command completes automatically.
