Geometric Dimensioning & Tolerancing (GD&T)
Geometric Dimensioning & Tolerancing is an engineering tool used to accurately describe parts and manufacturing tolerances. GD&T symbols are introduced and then used during the course to describe part forms and datums. Tolerance specification for form, orientation, location and runout are presented.
