The Journeyman's Guide to Geometric Dimensioning and Tolerancing: GD&T for the New Millennium

The Journeyman’s Guide to Geometric Dimensioning and Tolerancing: GD&T for the New Millennium is a practical reference for engineers, designers, and quality teams who need GD&T to be clear and verifiable—not open to interpretation from one reviewer (or supplier) to the next. When drawings include interacting controls, complex feature relationships, and multiple functional requirements, a solid reference helps teams stay aligned on what the callouts require.

Use this guide as a desk-side resource during drawing reviews, design changes, supplier conversations, and inspection planning. It’s especially helpful when you need to sanity-check a feature control frame, confirm how a requirement should be established from its datum features, or keep internal terminology consistent across design, manufacturing, and inspection. Clear application of GD&T reduces the back-and-forth that often happens late in the process—because the requirement was communicated correctly in the first place.

This book is a strong fit for:

• New GD&T users who want a structured reference they can return to
  
  

• Experienced users who need a fast refresher
  
  

• Teams standardizing how they apply datum reference frames and evaluate conformance
