Geometric Dimensioning & Tolerancing - Level I
I.D. # 86020 Duration 3 Days

Save time and money, while increasing quality and productivity by mastering this important and internationally-accepted engineering communication system. Geometric Dimensioning and Tolerancing (GD&T) is based on ISO standards and the ASME Y14.5M-1994 Dimensioning and Tolerancing Standard.

Seminar attendees will have a unique opportunity to meet one-on-one with the instructor, with time to discuss problem drawings in a focused setting, and will receive a copy of the ASME Y14.5M-1994 Dimensioning and Tolerancing Standard and handout material specially prepared for this program.

Attendees are encouraged to bring problem drawings as they will have several opportunities during the workshop to meet with the instructor individually.
Learning Objectives
By attending this seminar, you will be able to:
  • Learn effective use of the standardized accepted symbolic design/engineering language
  • Enhance your ability to communicate and interpret specifications on engineering drawings and to replace instructions that are often misunderstood
  • Improve communications and relations among design, engineering, manufacturing, and quality control personnel
  • Eliminate translation errors with international affiliates
  • Save time, reduce costs, and increase productivity
Who Should Attend
This workshop is designed for those who are involved in any area of engineering, drafting, design, quality control, inspection, tool or gage design, machining, or estimating where communication by engineering drawings is involved. The workshop is designed to teach the beginner the fundamentals of the system while giving the experienced user a better understanding of the more difficult applications.
Seminar Content
