GD&T Skills Survey
The GD&T Online Skills Survey is the latest in a series of free resources available from ETI. The survey measures an individual's skill level in the application and interpretation of geometric dimensioning and tolerancing, based on Y14.5M-1994. It is designed to help users assess which GD&T topics they understand and what amount of GD&T training is needed.

The survey was developed by ETI's founder, Alex Krulikowski, a GD&T expert with over 30 years of industry experience. The online 25-question survey takes minutes to complete. It can be used by individuals for personal assessment or by companies who would like to test whole departments.

GD&T Potential Cost-Saving Calculator
The GD&T Cost-Saving Calculator is the latest free resource from ETI. The calculator is a tool that helps companies understand the amount of unnecessary expenditures each year due to employees not knowing how to correctly apply and interpret GD&T.

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

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

Click here to try the
GD&T Potential Savings Calculator

The calculator can be used at the company, division, department or project level. It analyzes your data and estimates the annual savings your organization will realize in each aspect of design, inspection, and production. Enter information for whatever scope of analysis you wish to perform.Tool tips provide assistance with understanding data entry.

Even if you estimate conservatively, you'll be amazed at the impact GD&T will have on an organization's ability to cut costs.

The Digital Tolerancing Forum
Although many companies are working on implementing model-based tolerancing, there is no forum to discuss technical issues, and lessons learned. To develop an accurate view of the state of the technology, and understand the technical issues and lessons learned in implementing model-based tolerancing, I have established a Digital Tolerancing Forum.

The Forum is comprised of individuals using various CAD Systems in the transition from 2-D drawings to using model-based tolerances. The forum shares information on the capabilities, technical and implementation issues, and uses of digital tolerance information.
