ETI Celebrates 20 Years Providing GD&T Products and Services

Effective Training Inc. has been providing geometric dimensioning and tolerancing (GD&T) products, training, and resources since August 1985. GD&T is an international language of symbols used on engineering drawings by thousands of companies worldwide to save time and money in the design and manufacturing process.

WESTLAND, Michigan - (August 2005) - Effective Training Inc. (ETI) is celebrating its twentieth year as a GD&T training and consulting corporation by offering a 20% savings on select products. GD&T stands for geometric dimensioning and tolerancing, an international language of symbols used on engineering drawings to communicate design intent. It is used by thousands of manufacturers worldwide.

ETI was founded by Alex Krulikowski as a one-man operation in August 1985. The company now employs a team of professionals that provide GD&T products and training to thousands of organizations worldwide. The company's textbooks and other teaching materials are used in hundreds of educational institutions in the US, Canada, and overseas. Their self-study course and pocket guide have been translated into Spanish.

In the past 20 years, the name Krulikowski has become synonymous with GD&T. As a world renowned geometric tolerancing expert, he has often been referred to as "the doctor of dimensioning." He is the member of many national standards organizations, including the ASME Y14.5 Committee on Dimensioning and Tolerancing, and he served for six years as chairman of the Y14.41 Committee on Solid Model Dimensioning. He has published over 20 books and articles about GD&T, has created a dozen GD&T-related courses, and has developed a wide variety of products devoted to learning the topic.

"For me, the rewards of teaching go beyond the financial benefits," said Krulikowski. "I know that by teaching GD&T, I am providing the tools to help people grow and gain skills that will help them for a lifetime. It is a very satisfying career."

As technology has evolved, the demand for new types of GD&T training options has risen. In the past 20 years, Krulikowski has developed GD&T self-study courses, a video series, digital instructor kits, and a computer-based training program that has been sold to corporations worldwide. In 2003, ETI produced the GD&T Trainer Professional Edition, a new level of computer-based training that includes technical animations, audio narration, 3-D drawings, and other advanced features. This year, ETI unveiled their Fundamentals of GD&T web-based training [].

ETI provides GD&T onsite workshops to companies around the globe. They also offer a series of public workshops open to individuals throughout the United States that includes Krulikowski's new one-day Y14.41 solid model tolerancing workshop. It's the only course available that teaches the new international standard covering the use of GD&T on digital drawings. All of ETI's workshops are "hands-on" and based on adult learning principles.

ETI's website provides a variety of free GD&T resources, including an online newsletter, a discussion board, tech papers, a digital tolerancing forum, and a complete catalog of GD&T products that can be purchased through their online store.
