## Dimensioning Angularity

Looking for XactMeasure GD&T dimensions? If so, see:

- Using Feature Control Frames
- GD&T Dialog Box

Dimension Angularity dialog box

The Insert | Dimension | Angularity menu option computes the angularity error of a plane or line to a datum plane or line. (If only one feature is selected or keyed in, PC-DMIS uses the current working plane as the datum.)

Similar to perpendicularity or parallelism, the Angularity dimension allows you to specify an angle that isn't 90 degrees (perpendicularity) or 0 degrees (parallelism). For example, if you specify a 45 degree angle, PC-DMIS creates a tolerance band at 45 degrees, and checks that the hits are within that tolerance band.

The measured value is an angle (blue). The angularity's tolerance band is two parallel lines or planes (black) that never meet.
