Wrap-Up & Your Next Step
Books are essential—they give you foundational depth and reference you’ll return to repeatedly. But books alone are not enough for full competence, especially in applying GD&T.
If you want a structured path combining hands-on practice, feedback, modern curriculum, and both ASME + ISO coverage, you should pair your reading with a robust course like Excedify’s GD&T Training Certification.
