Geometric dimensioning and tolerancing can solve many of your company's design problems and save your company thousands of dollars. Let ETI show you how to properly apply and interpret GD&T. Call 800-886-0909 today to learn more.


Do all your suppliers know GD&T?

Drawing specifications are often misinterpreted after release.

How can you be sure that your suppliers will provide you with the part you need?
How can you decrease your rejection rate?

If companies, suppliers, and manufacturing possessed the same skill levels as the people creating the drawings, your company could eliminate up to 50% of the meetings needed to re-explain drawing intent.

When your suppliers know GD&T, you eliminate guesswork and erroneous assumptions, because using GD&T correctly provides uniformity in the specification and interpretation of the drawing. Suppliers who use GD&T will be working in the same "language" as your design team.

When you and your supplier speak the same language, they understand the part you want, and you get exactly what you need.

Encourage your suppliers to learn geometric tolerancing fundamentals. Once they know GD&T, your rejection rate will be reduced, saving your company both time and money.

Working from vague drawings?

drawing errors
Tired of finding drawing errors after it's too late?

Vague drawings lead to errors that become more costly to an organization at each stage of the product development process. Using GD&T in the design stage will reduce drawing errors and eliminate the problems and costs that multiply when communication fails between production stages.

If found at the design stage, a vague drawing can be corrected for a few dollars. In the model shop, it can cost hundreds of dollars. However, once the drawing gets to production, the expenses escalate quickly. Gaging, tooling, and scrap costs can bring the total to 100's of thousands of dollars.

How can you eliminate these costly errors?

When your design team uses GD&T, the result is drawings that communicate specifications more uniformly. Used correctly, geometric tolerancing reduces vague drawings and the controversy, guesswork, and assumptions they cause throughout the manufacturing and inspection process.

Since working with engineering drawings involves analyzing, making decisions, and processing data, everyone on your design team should learn more about proper drawing specifications and GD&T. ETI’s Engineering Drawing Requirements workshop is based on practical application of drawing interpretation. It will give your team a better understanding of the view representation, dimensions, tolerances, and symbols used on drawings.

Eliminate the vague drawings that cost your company time and money. Make sure your design team understands proper drawing specifications and learns GD&T fundamentals.

Difficulty communicating drawing requirements?

designer's intent
Can't understand the designer's intent?

If you find that your company spends time and money in meetings to discuss drawings, scrap costs, and gage rework, then you need to improve the way your drawings communicate.

Because GD&T provides uniformity in drawing specifications and interpretation, it clearly conveys the drawing requirements so you understand the designer’s intent. Correctly applying GD&T to engineering drawings reduces controversy, guesswork and assumptions. As a result, you’ll spend less time in meetings because design, production, and inspection will all be working in the same language.

A better understanding of drawing interpretation and GD&T can decrease costs associated with:

  • Creating, interpreting and revising drawings
  • Communicating or interpreting design requirements for suppliers and manufacturing
  • Manufacturing expenses

The costs of poor drawing communication can equal many times the cost of GD&T training. GD&T is used by about one-half of the world's manufacturers because it allows communication among all levels and functions within a company, as well as with their customers and suppliers. Its philosophy is pro-profits and pro-growth.

Wasting money on parts that don't fit?

A successful design creates a product that:

  • Contains parts that fit together well
  • Performs desired functions efficiently
  • Maximizes tolerances to create a cost-effective manufacturing part

Using GD&T and tolerance stacks on your drawings is essential to creating a successful design. GD&T used properly can eliminate vague drawings, and calculating tolerance stacks will reduce drawing errors. The correct application of GD&T and stacks will eliminate the problems and costs that multiply when communication fails between production stages.

The practice of tolerance stacks is essential to good product design because stacks studies the design from the viewpoint of form and function, design and manufacturing. Stacks bring logic and order to the design process.

Tolerance stacks helps you optimize part tolerances. Stacks help you:

  • Increase your understanding of part function
  • Discover and resolve problems on paper rather than in prototype or production
  • Make intelligent design decisions
  • Evaluate proposals and change requests
  • Increase your understanding of geometric tolerancing

Use tolerance stacks to solve problems in the design stage instead of the production stage. Stop wasting money on parts that don't fit. Use tolerance stacks and get it right the first time.

Just knowing the symbols isn't enough.

You know GD&T, but do you know how to apply it?

People often think they "know" GD&T after studying a chart or reading a pocket guide and memorizing the symbols. A quick study of geometric tolerancing basics cannot compare to a complete course taught by an instructor who has experience using GD&T on the job.

All of ETI's courses were developed by GD&T expert Alex Krulikowski, a degreed instructor with over 30 years of experience using GD&T on the job. His books, workshops, and computer-based training program teach how to apply GD&T in industry. GD&T training and products from ETI will help you to achieve a better understanding of how to apply GD&T.
