IIGDT World International Institute of
Geometric Dimensioning & Tolerancing
 
 
Level 2
GD&T – Intermediate Principles
Course Outline

Course Objective

To provide a foundational understanding (interpretation) of mechanical drawings using linear tolerancing and GD&T in the design, manufacture and inspection of parts, which have geometric controls applied per ANSI / ASME or other national standards.

Targeted Audience Any individual who must have the ability to “interpret” mechanical drawings using linear tolerancing and GD&T. Any manager with direct or indirect responsibility for product development, manufacturing, quality, customer interaction or supply chain management. Engineers of all technical disciplines, mechanical designers & drafters, mechanical inspectors & technicians, metrologists, machine operators, tool makers and statisticians who analyze data from mechanical components.
