Dimensioning
Orthographic and isometric views define the shape and general features of the object
Dimensioning adds information that specifies Size of the object Location of features (e.g. holes) Characteristics of features (e.g. depth and diameter of
hole)
Dimensions also communicate the Tolerance (or accuracy) required

Scaling vs. Dimensioning
Drawings can be of different scales, but dimensions are ALWAYS at full scale.
