training and referencing online.

We make absolutely sure what we teach is
what you actually need in the real world.

Whether you are new to GD&T or have a full engineering background, our site provides the most valuable resource for training and reference that you will find anywhere. GD&T is a system of symbols and features used in machining, manufacturing, quality and design that specify the shape, orientation, size, and critical features of the object of the drawing. GD&T is used to ensure that everyone is on the same page regarding how a feature or part is defined.  

When a design engineer hands off a drawing to a machinist, they need a common technical language for communicating exactly what must be done. GD&T is a system to regulate and determine that communication.

New Announcement:

We are beginning to roll out a new training program for specifically aimed at college and entry-level engineers. We are going to be expanding our GD&T program considerably to include the most important topics that all mechanical engineers must understand when working professionally.

What Is GD&T?

GD&T is the overarching language used in design, manufacturing and quality inspection. GD&T combines a set of symbols, rules and principles to ensure that everyone is on the same page regarding how a feature or part is defined.  When a design engineer hands off a drawing to a machinist, they need a common technical language for communicating exactly what must be done. GD&T is a system to regulate and determine that communication.

Why Is GD&T Important?

GD&T is very important to the engineering world. It is critical for anyone seeking employment in the mechanical engineering field to understand it. Whether you are an automotive engineer or a CNC machinist, knowing the basics of GD&T is paramount to having success in your industry.

Designers, engineers, machinists, inventors and CNC operators all need a grasp of GD&T knowledge to communicate clearly with each other.

One of the biggest problems is that people think GD&T is overly complicated and hard to learn. While there is a lot that goes into mastering GD&T, the overall concepts and basics of all the symbols are actually quite simple to learn.

We don’t just throw every concept at you – we make absolutely sure what we teach is what you will actually need in the real world.

using GD&T at work engineers and machinists

We know that designers, engineers, machinists, inventors and CNC operators all need a grasp of GD&T knowledge to communicate clearly with each other.

Are you taken aback by how much information there is and what you need to learn when it comes to GD&T?

Other GD&T training courses only overwhelm their students by providing every possible concept, including useless information that they will never need.

Don’t be confused any longer!

Our GD&T training course will provide JUST the info you need in a clear, concise manner.  

In addition, our course will be on demand and available whenever you are.  We will give you the confidence and the knowledge you need to to work with GD&T in the real world.
