This function enables the user to measure the angle in degrees between two selected vectors.

After selecting the function, the Input Coordinate dialog box is displayed. The user needs to define two vectors by selecting 4 points/nodes. eta/DYNAFORM displays the measurement of four angles in the message prompt window in the following format:

ANGLE=69.90, TOP: 72.49, SIDE: 3.41, REAR: 124.78

Angle indicates the angle between two vectors. Top value indicates the angle between the projection of two vectors on the global XY-Plane. Side value indicates the angle between the projection of two vectors on the global XZ-Plane. Rear value indicates the angle between the projection of two vectors on the global YZ-Plane.
