## Dimensioning Concentricity

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

Dimension Concentricity dialog box

If a sphere is selected as the first feature, the second feature must also be a sphere. PC-DMIS will then three-dimensionally calculate the concentricity between the two features. | The Insert | Dimension | Concentricity menu option calculates the concentricity of two circles or cylinders, cones, spheres. The second feature that is entered is always the datum feature and may be a line feature that represents an axis. If only one feature is selected, the current working plane becomes the datum feature. This dimension type is considered one sided, meaning a single positive value tolerance is applied.
