This 3-day advanced-level course teaches the advanced concepts of GD&T as prescribed in the ASME Y14.5M-1994 Standard. It can be conducted with flexible scheduling, including 5 mornings or 5 afternoons.¿¿¿

• Product design and functional dimensioning,
• Feature and feature of size
• Dimensioning standards on drawings
• Rigid and flexible (non-rigid) parts
• Requirements for parts measured in the restrained state
• Datum usage on restrained (non- rigid) parts
• Calculating advanced applications of form controls
• Uses, advantages, misconceptions, and common errors of the datum system
• Nine common datum feature types
• Advanced datum target concepts
• Modifier usage in tolerance of position applications
• The effects of simultaneous and separate requirements with tolerance of position
• Composite and multiple single-segment position and profile tolerancing
• Profile applications

• The fundamentals of drawing interpretation and how to handle substandard drawings
• How to specify/interpret specialized datum feature applications
• Interpreting tolerance of position applications with a conical tolerance zone
• More than 50 additional exercises

Newly acquired learning is reinforced throughout the class with more than 250 practice problems.
