Probing and Measuring Features

Probing angles

A minimum of four probed points are required to measure an angle. The points must be probed in a pre-
scribed 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 here, the correct pattern of points probed for an angle is:
• A minimum of two points well distributed along the reference side, followed by
• A minimum of two points well distributed along the opposite side of the included angle
The View window shows the feature and the points used to define it. The DRO window shows the number
of points probed, the coordinate location of the angle and the angle orientation to the skew axis.

The included angle is shown as the default measurement result, however, the angle type can easily be
changed by selecting the desired angle type from a menu of alternatives in the DRO window.
