Dimensions in a drawing will typically be on their own layer. The dimension commands make adding the measurements easy and accurate since the design should already be drawn to-scale. The dimension options below are the most commonly used:

Linear - Creates a horizontal or vertical dimension line

Aligned - Creates a linear dimension line that is parallel with the defined endpoints

Angular - Creates a dimension for the angle between two objects

Radius - Creates a radius dimension for an arc (includes the radius symbol)

Diameter - Creates a diameter dimension for a circle (includes the diameter symbol)
