New Search Ellipsoid

In orebody modelling the orientation of the mineralisation can be represented in terms of a 3D ellipsoid. Ellipsoids have three axes that are always mutually perpendicular, each of which can be treated as a linear feature.

On the Block Model tab, in the Search group, click New Search Ellipsoid to interactively create and orientate a search ellipsoid around reference data.

You will be prompted to create a new form set.

If the data search form set you specify already exists, you will be prompted to overwrite it or cancel.

The simplest way to set up a search ellipsoid is to define the azimuth and plunge of Axis 1, and the rotation of Axis 2:

When a new search ellipsoid is created:

  1. the ellipsoid is displayed in the centre of the view
  2. the view is oriented to allow Azimuth adjustment (Plan view)

    3. You are prompted to define the Azimuth by dragging the axis lines. Axis lines that point in the negative (-ve) directions are drawn as dashed lines:

  1. The view is oriented to allow Plunge adjustment (Looking West as defined by the Search Ellipsoid)

    2. You are prompted to define the Plunge by dragging the axis lines:

    Right-click to advance to the next step.

  1. The view is oriented to allow Rotation adjustment (Looking South as defined by the Search Ellipsoid))

    2. You are prompted to define the Rotation by dragging the axis lines:

    The interactive search ellipsoid rotation is locked to this axis and you can not rotate around any other axis.

    Right-click to finish creating the search ellipsoid.
