You can do this in the following ways:
- right-click in the view, then select Legend Options > Major Planes from the popup menu
- select the Major Planes plot button in the toolbar or the View menu
- use the Plot Option checkboxes in the sidebar, and use the Legend and/or Planes options to customize as required
If the plane orientation format is not Dip/DipDirection (eg. Trend/Plunge) then click on the Convention option in the lower right corner of the screen, and toggle until Dip/DipDirection format is displayed.
In addition, you can toggle the display of weighted or unweighted planes with the Terzaghi weighting option in the sidebar or the View menu.
