Measure Angle

The Measure Angle option allows you to calculate the angle between any two points (planes) on the stereonet.

To use the Measure Angle option:

1. Select Measure > Angle from the Tools ribbon.
2. Left-click at a point (pole) on the stereonet. Remember that the cursor coordinates are always displayed in the lower-right corner of the Status Bar.
3. Left-click at a second point (pole).
4. The Measure Angle dialog will immediately appear, displaying:
   1. The acute and obtuse angles between the two points (poles) selected.
   2. The coordinates of the two selected points are also displayed, in the format corresponding to the current Reporting Orientation Convention (i.e., Trend/Plunge, Dip/Dip Direction, Strike (right)/Dip, Strike (left)/Dip).
5. Modify the points by entering the coordinates or graphically by left-clicking and dragging the pole handles. The result is immediately calculated and displayed in the dialog.
6. Click OK to finalize the Measure Angle entity.
