Typically, when authoring work instructions, production routers, or other engineering documents, I am accustomed to enclosing quantities within parentheses within sentences. "Drill Ø.250 hole (6) plcs." would be commonly used nomenclature. Lately, a coworker is critiquing my work and swears by the concept of using numeric values without parentheses for values up to ten, and the spelled out word, followed by the same value in parentheses, for values greater than ten, as in "Chamfer .030 x 45° four plcs." Can anyone shed some light on the commonly preferred practice for engineering documentation?
