New Ellipsoid

To access this dialog:

Run the command "new-ellipsoid"

This dialog is launched by the new-ellipsoid command is used to create one or more search ellipsoids, for inclusion within a new or existing ellipsoids object.

If you wish to store your ellipsoid definitions within an existing ellipsoids object, you can select it first. Otherwise, you can create a new ellipsoids object automatically. Alternatively, use the Current Object toolbar to generate a new, empty ellipsoid object before you start.

Then, you can define your ellipsoid centroid position by either specifying values in the relevant coordinate fields, or you can pick a position on the currently active 3D section. Define the size and orientation of your ellipsoid, then click Add to add it to the currently specified ellipsoids object (an object can contain one or more ellipsoid definitions).

Field Details:

Ellipsoid Object: select an existing ellipsoid data object or enter a new description to create a new object. All ellipsoid objects that are currently loaded will be displayed in the drop-down list.

Copy from loaded ellipsoid: if you wish to retrieve the properties of an existing ellipsoid (say, to create a modified copy), select the pick button and then an ellipsoid in view in any 3D window. The properties of the ellipsoid (see below) will be transferred to the New Ellipsoid dialog.

Position: enter the X, Y and Z coordinates for the centroid of an ellipsoid. You can also use the picker button to select a 3D location in the current 3D view.

Size: enter a Length for the major, semi-major and minor axes of the ellipsoid. This determines the overall size of your ellipsoid.

Rotation: enter the Azimuth, Dip and Roll of the new ellipsoid. You can specify the axis for each angle independently using Axis 1, Axis 2 and Axis 3.

Add: add the new ellipsoid definition to the current ellipsoids object.
