driven dimension

A dimension whose value depends on the value of other dimensions or elements. The value of a driven dimension is controlled by the element it refers to, or by a formula or variable you define.

When a dimension is driven, and faces connected to the dimensioned edge are modified, the dimension value is allowed to change.

It is easy to identify a driven dimension:

• In a modeling environment, the default color of a driven dimension is blue. In draft, the default color is dark cyan. You can modify the default display color of driven dimensions.

• On dimension editing command bars, a driven dimension is identified by the unlock icon .

To learn more about the characteristics and benefits of driving dimensions, see the Dimensioning overview topic and PMI dimensions and annotations.
