Angles
Four probed points are required to measure an angle. The four points must be located in a prescribed
pattern, on the two lines that form an angle. There is no practical limit to the number of points that can be
probed, and in general accuracy is increased by probing more points.
As shown above, the correct pattern of points probed for an angle is:
• Two points well distributed along the reference side, followed by
• Two points well distributed along the other side of the included angle
Measurement results are
shown in the Features tem-
plate, Part View window and
Results window. The Results
window shows the feature
identification number, the
number of features used in
the measurement, the includ-
ed angle and the coordinate
orientation of the angle.
The included angle is shown
as the default measurement
result, however, the angle
type can easily be changed
by right-clicking the Results
window and selecting
the desired angle.
Probe the first two points on the reference side... then probe two points on the other side
of the included angle
