Drawings are the final line of defense between a good product and a costly production mistake. Dimensioning is not an administrative task — it is the language of functionality.
Controlling what truly matters
Not everything needs to be tightly controlled. Only what affects function or assembly:
• mating surfaces
• assembly alignments
• critical tolerances
• tool accessibility
Functional datums as the foundation
A drawing with clear references shows where the truth lies. Logical datums keep a design controllable — even when processes vary.
Good dimensioning is the difference between a predictable product and a gamble.
