Dimensions Dimensions are used to describe the sizes and relationships between features in your drawing. Dimensions are used to manufacture parts and to inspect the resulting parts to determine if they are acceptable. Drawings with dimensions and notes often serve as construction documents and legal contracts. ANSI Y14.5M-1994 is the current standard. Other standards may apply.
