Advanced Geometric Dimensioning and Tolerancing

COURSE DESCRIPTION

Advanced Geometric Dimensioning and Tolerancing is taught in a problem solving team format that will stimulate discussion and provide participants with the tolerancing tools and techniques to:

  • Design and interpret drawings requiring complex GD&T concepts
  • Focus on practical applications of GD&T for mating parts
  • Communicate design intent to persons in manufacturing and inspection
