Measuring Angles
Measures the angle between three points, or between two lines.
- Select three points that define the angle you want to measure.
- The angle is measured and displayed. It is calculated according to the order of selected points.
The angle is also displayed in the Measurement Info Palette.
Local menu option:
  By Entity: Measures the angle between two lines. The lines must intersect (this tool does not infer where extensions of lines will meet).
- Select the first line. The point you select on the line defines the angle that will be measured.
- Select the second line, and the angle is displayed.
In this example, if you selected the lines in a different location, you will measure a different angle.
