The requirement to manufacture interchangeable parts was a key factor that favored the growth and development of the drafting profession.1

By necessitating the production of identical components that could be substituted for one another, this manufacturing shift moved the responsibility for defining exact sizes, shapes, fits, and clearances away from individual artisans and onto designer-drafters. Previously, artisans often determined these technical details while custom-building each item; however, the move toward mass production required these specifications to be clearly documented in advance. Consequently, drafters were required to refine their skills to produce precise, comprehensive drawings that could communicate engineering intent to fabricators without the need for further decision-making on the shop floor.123
