Introduction to GD&T

Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation.

WHAT IS THIS WORKSHOP?

Geometric dimensioning and tolerancing (GD&T) it tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. AKA  Engineering Tolerances. 

In this class we’ll learn the basics of how to give dimensions and tolerances, read from drawings, and make CAD File With GD&T! By the end of this workshop, you’ll be able to read engineering drawings and understand what GD&T is all about.

WHAT DO I NEED TO BRING?

You’re welcome to bring along and use your own. If you’re a note-taking type, bring something for that too!

WHO IS THIS WORKSHOP FOR?

This workshop is for absolute beginners and doing or passed Mechanical Engineering, and no prior experience is necessary.

What is GD&T?

It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. GD&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features.
