Add Dimension

Use Add Dimension to add  a Linear or Angular Dimension to or between sketch-elements.

Dimensions include the:

Distance between Points*

Length of a Line** ; Radius of a Circle or Arc.

Perpendicular (shortest) Distance from a Point* to a Line**, X-axis, or Y-axis.

Angle between two Lines, or the Angle from the X-axis or Y-axis to a Line**

Angle between three Points*

* Point, start-Point, end-Point, and center-Point.

** Line or CAD-Line


Usually, do not make a dimension zero. It is better to add a constraint. See Sketch-Constraints
