Design Size: The design size of a dimension is the actual size of the design, including an allowance for fit and toler-

ance.

Typical (TYP): When specified after a dimension, this indicates the repeated design size if a tolerance is specified

or repeated basic size if a tolerance is not specified.

Reference (REF): The reference dimension is an untoleranced dimension used for informational purposes only. It is

a repeated dimension or one that can be derived from other values in the drawing.
