## Dimensioning Parallelism

Parallelism dialog box

The Insert | Dimension | Parallelism menu option measures the parallelism between two features. The second feature is always the datum feature. When 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.

Note: The evaluation of parallelism is 3-dimensional regardless of the workplane or the feature being dimensioned.
