5. The Lines or linked Origin, Found Arc, and Intersection are displayed on the image.
6. If you check the Enable Angle Check check box, the tool will fail if the Actual Angle value is not
within the Angle Range limits. Enter the desired values in the Minus, Nominal, and Plus fields.
7. Select the angle Direction from the drop down (Clockwise or Counterclockwise). The selection deter-
mines where the angle measurement starts and ends, and the Arc ROI is displayed with the arrowhead
pointing in the selected direction. Whether you choose CW or CCW, the measured Angle will always
be a positive number from 0 to 360.
8. Select the desired Endpoint. This allows you to choose to whether or not to consider the direction of
the ending line when measuring the angle. Sometimes line orientation is ambiguous at 180 degrees
rotation. For example, the major axis of a blob does not have 360 degrees of rotation, only 180 degrees.
In this case, choose "Shortest Angle to Ending Line" and the tool will ignore 180 degree rotations of
the ending line and always measure the shortest angle to the line.
