Course description

Advanced Geometric Dimensioning and Tolerancing is a problem–solving course that will 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

Suggested participants

• Mechanical Engineers
• Design Engineers
• Draftspersons
• Quality Engineers
• Manufacturing Engineers
• Quality Inspectors
• Machinists
• Anyone who may be required to produce or interpret complex engineering drawings

Course format

This course is presented in a problem solving, team format. Each team will present its best solution on an overhead transparency. Then the merits of each solution will be explored in a class discussion.
