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 template, Part View window, Results window and Feature
Stamp 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.
Fifty points are probed using the Buffer probe on
the reference side...
