Organizations today are increasingly designing, building, and inspecting parts using ASME Y14.5M-1994 as well as the ASME Y14.5-2009 standard. Many more organizations are in planning stages for a multi-standard future. But having the fundamental learning, comparison, and references materials for both standards in a single self-paced learning environment has not been available… until now.

ETI’s eLearning System gives those responsible for GD&T skill development a comprehensive solution for fundamentals training in both standards, comparison instruction to understand the differences, and access to powerful GD&T dictionary, quick reference, and skill survey tools.

The package includes three fully interactive, narrated courses. Two courses teach the fundamentals of geometric dimensioning and tolerancing, including the symbols, modifiers, rules, and concepts of GD&T. The courses are based on the ASME Y14.5 1994 and 2009 standards.

The third course in the package is the ASME Y14.5 Standard Comparison. This course covers more than sixty significant revisions, additions, and deletions from the 1994 to 2009 standard. You'll learn how the subject matter has been reorganized, and about new sections that have been created for profile, orientation, and form.

A valuable tool for individuals who create or interpret engineering drawings:
Product and gage designers | Process engineers | Product engineers
Manufacturing engineers | Supplier quality engineers | CMM operators
Buyers | Purchasers | Checkers | Inspectors | Technicians | Sales engineers

Screenshots and Animations
Courses in the eLearning System feature detailed, colorful lesson screens, with full color animations that demonstrate concepts and help students visualize important topics.

Lesson screens encourage student interaction, and include 3D solid part examples.

The software can be used to learn GD&T, brush up on skills, for certification, and as a resource when training is done.

The software can be used as:

  • A beginning course in GD&T
  • A geometric tolerancing seminar
  • A supplement to live training
  • A review after training
  • An internal GD&T certification
  • An on-the-job reference

The ETI eLearning System contains three GD&T Trainer courses.

With participant-focused lessons, user-friendly navigation, and detailed full-color graphics, the three courses in the ETI eLearning System rival the classroom for expertise, consistency, convenience, and affordability. The software provides a ‘hands on’ approach to learning with animations that show exactly how a symbol is interpreted. Users can visualize a concept and understand it more easily, and—best of all—learn at their own pace.

GD&T Fundamentals 2009 – This course in the fundamentals of GD&T based on ASME Y14.5-2009 includes 29 lessons, numerous exercises, 29 quizzes, and a final exam.

GD&T Fundamentals 1994 – This course is similar to the 2009 version, but is based on ASME Y14.5M-1994. It includes 28 lessons, numerous exercises, 28 quizzes and a final exam.

Both courses allow the option of utilizing the seminar version - with lessons taken in any order and a printable certificate of completion when all lessons have been completed.

There is also a class version where the quizzes must be successfully completed in order to progress to the next lesson. These courses include:

- GD&T Fundamentals Class
- GD&T Fundamentals Seminar
- Skills Survey
- Certification Test
- Quick Reference
- Digital Design Dictionary

ASME Standard Comparison Y14.5M-1994 to Y14.5-2009 – The new ASME standard contains numerous changes that affect the specification and interpretation of geometric tolerancing. This course contains an introduction section and nine lessons with quizzes. The course includes:

- Digital Design Dictionary

The minimum passing score for the quizzes and final exam can be set through the Course Administrator. A certificate of achievement may be printed after the class version is complete.

Course Administration Tools

The eLearning System contains newly updated course administration tools that help track student progress. The Course Administrator allows changes to course options and assignment of student passwords. When a student works a lesson, a record of his/her performance is saved in a log file that lets administrators monitor student progress. The Course Reporter allows you to print and export various reports on student progress.

  • Student/course records stored in MS Access database
  • Holds up to 2,000 students
  • Additional fields can be added to log-in screen
  • Set automatic time-out feature for lessons
  • Simultaneous record access for multiple admins
  • Additional student/company info storage
  • Limit student access when more than 1 course
  • Report generator tracks students and courses
  • Set min. passing scores for lesson quizzes/final
  • Password protect student records
  • More than 90 different report types 

The eLearning System is available in a LAN (Local Area Network) platform.

elearning system packgeThe ETI eLearning System is available in a LAN version which is perfect for companies that want to maximize employee time, because it allows multiple professionals to train concurrently, right from any Windows-based PC.

The administrator can register students and track individual results, but there is no need to create training schedules, since this version allows employees to train simultaneously at their own workstations.

(This version allows registration and training by multiple users on a LAN system, depending upon amount of seats purchased.)
