# Fundamentals of GD&T 2018 3-day

This course teaches the terms, rules, symbols, and concepts of GD&T as prescribed in the ASME Y14.5-2018 Standard.

This course offers an in-depth explanation of geometric tolerancing symbols, their tolerance zones, applicable modifiers, common applications, and verification principles. The class includes a comparison of GD&T to the directly toleranced dimensioning method; Rules #1 and #2; form and orientation controls; tolerance of position; runout and profile controls. Newly acquired learning is reinforced throughout the class with more than 150 practice problems.

Each attendee receives a Fundamentals of Geometric Dimensioning and Tolerancing 2018,  Using Critical Thinking Skills textbook by Alex Krulikowski (Based on the ASME Y14.5-2018)

Students who attend courses like this one walk away with more than knowledge - they gain on-the-job skills because the learning materials are performance-based and taught by industry professionals.

## What Will You Learn

By attending this class, you will be able to:
• Explain the importance of standards on engineering drawings
• Describe the types of dimensions, tolerances, and notes
• Explain why GD&T is superior to the directly toleranced dimensioning method
• Describe the general dimensioning symbols
• Define the key terms used in GD&T
• Recognize the symbols and modifiers used in GD&T
• Explain the rules used in GD&T
• Describe the concepts of worst-case boundary, virtual condition, and bonus tolerance
• Interpret the various types of geometric tolerances (flatness, circularity, cylindricity, straightness, perpendicularity, parallelism, angularity, position, runout, and profile)
• Describe the datum system
• Interpret applications of datum targets, size datum features at RMB, and size datum features at MMB
