This tool allows the angle of any line or Bezier relative to the horizontal to be calculated. The direction of the entity picked is significant. Alternatively, the sweep angle of an arc can be calculated.
After activating the tool, pick the Bezier, line or arc. In the case of a line or a Bezier the angle of the entity is defined as the angle from the entity start to the entity end. In the case of an arc the angle is defined as the angle subtended at the centre of the circle of which the arc is a segment.
The measured angle will now be displayed on the Edit Bar and in the Output toolbox.
