Add a Plane to Stereonet

Adding a plane to a stereonet will result in a great circle being drawn and its pole.

Great circles can be used to visualise the orientation of the plane or joint set on a stereonet. A great circle can also be created from a cluster of projection poles and thus display an average plane for the cluster.

Note:  Prior to creating great circles, a stereonet must be created.

  1. Display the stereonet in a view window.

  2. Display the fitted planes in a separate view window.

  3. On the Geotechnical ribbon tab navigate to the Stereonet group and select Add plane.


  4. Using the facet selection tool , highlight the plane (or highlight a discontinuity object) to be used to create the great circle. The Dip angle and Dip direction are automatically populated.

    5. Note:  If more than one object is selected, the mean orientation is used.

  5. Select whether to Display pole or Display plane. Select another colour if desired. Enter a location for the plane, if desired.

  6. Click OK or Apply.

    The great circle is saved in the stereonet container specified in the Destination stereonet field.
