### Relationship for Angle Between Dimensions

The Relationship area of the dialog box allows you to specify whether the Angle dimension can calculate the angle between two features, or between one feature and a particular axis: X axis, Y axis, and Z axis. As soon as you select at least one feature for the Angle dimension, PC-DMIS fills in the boxes next to the option buttons with the computed nominal angle values.
