Angle
The Angle tool calculates and displays the measurement of an angle defined by an angle mark or
three selected points. The second point must be the vertex.
If you use Angle to select three points, angle measurements default to angles from 0 to 180 degrees
(interior angles). If you want measurements greater than 180 degrees (reflex angles), you must first
mark the angle with Mark Angle in the Display toolbox. The default measurement is displayed in
degrees. You can change its precision by using Numerical Edit in the Display toolbox.
You can add a comment to the measurement immediately after creating it by typing the text. See
" Comments" in the chapter "Using the Display Toolbox" for more information on adding a comment
to a numerical value.
Checking angles
1.
Select Angle from the Measure toolbox.
2.
If an angle mark is displayed on the angle, select the
angle mark to measure the angle. Otherwise, select
three points to specify the angle. The second point
must be the vertex.
Moving measurements
Reposition the measurement by selecting it with the Pointer
tool and dragging it to a new position.
The measurement moves with the object it measures
unless you pull it away. When you pull it away from the
object, the measurement momentarily resists before
pulling away.
