There are major benefits in our shrinking world derived from use of a single worldwide standard of drawing interpretation. Drafting callouts are a separate language that cross national boundaries. This paper will cover several aspects of GD&T parts produced by multiple processes as well as a study of an inseparable assembly.

Here are seven advantages that add up to significant savings in production:
