How are you going to get a better manufacturing job if you don't understand Geometric Dimensioning and Tolerancing (GD&T). Large, high paying manufacturers expect their engineers and production staff to have a working knowledge of GD&T. Now you can get the GD&T background you need without having to wait for on-the-job training.  

Fortunately the concepts of GD&T are intuitive and a working knowledge is failry easy to learn right from your own computer.

Haydenpub is now an i GET IT Reseller
 providing world class video training for manufacturing professionals.  For only $39 USD you get unlimited access to the best GD&T video training available.  

By signing up for one month of unlimited GD&T Training for only $39 USD you also get unlimited access to AutoCAD, NX, SOLID EDGE, Solid Works, CATIA v5 and V6 Video training. 


The program begins with a bit of the history of GD&T, then we look at the cost of designing and manufacturing a part. We will compare the “old” methods of dimensioning and Tolerancing to the Y14.5M approach. In this analysis, we will demonstrate the strengths and advantages of GD&T as a design tool, as a manufacturing aid, as a purchasing (estimator) aid, and as an overall communications facilitating tool. We incorporate many practical exercises to enhance learning, and to increase confidence.


A working understanding of technical drawings (perspectives, sections, details, etc.). GD&T Overview and Print Reading suggested.

Intended Audience:

This program is designed for anyone who designs, drafts, engineers, purchases, manufactures, estimates, or inspects parts and assemblies. Particular emphasis is placed on those who design and manufacture, and those responsible for quality.
Duration (hrs):  14
Skill Level: Appropriate for All
