Learn Geometric Dimensioning and Tolerancing (GD&T) in One Day with Exercises: Intensive Seminar
IR Engineer Education Research Institute will hold an online seminar to intensively learn the basics and practical application of GD&T (Geometric Dimensioning and Tolerancing), which is essential for creating unambiguous drawings that are globally applicable. The seminar aims to improve the accuracy of drawing creation and tolerance analysis for designers, manufacturers, and quality managers by explaining GD&T rules and interpretation with exercises.

IR Engineer Education Research Institute will hold a public seminar where participants can intensively learn the prerequisite skills for "GD&T (Geometric Dimensioning and Tolerancing)" in one day with exercises, which is indispensable for creating drawings with unambiguous interpretation and that are globally applicable.
Although the importance of geometric tolerancing was advocated by JIS in 2016, it is still not sufficiently widespread in the field. The recommendation states that unambiguous interpretation is guaranteed only when geometric tolerancing is applied, and it also points out the risk that Japanese drawings may become less acceptable overseas.
In global manufacturing, it is required to appropriately express drawings and consider tolerances, such as expressing functionally important "length and diameter" with size tolerances and functionally important "position" with position deviation.
Seminar Overview
Seminar Name: Basics and Practical Application of Geometric Tolerancing (with Exercises, Intensive One-Day Course)
Format: Online (Zoom LIVE streaming)
Date: June 24, 2026 (Wednesday) 10:00-17:00
Those who apply for this seminar can receive archived streaming as a special benefit from June 26 to July 10, 2026.
Tuition Fee: 49,500 yen (tax included) / per person (group discount available for multiple participants)
Instructor: Shohei Obata, Instructor (Representative of Obata Professional Engineer Office)
Course Details
This seminar will carefully explain the basic "rules of geometric tolerancing" and "their interpretation" for building a quality assurance system using GD&T, differentiating them from size tolerances.
The aim is to help all individuals involved in drawings, such as designers, manufacturers, and quality managers, correctly understand geometric tolerancing and apply it in practice to improve the accuracy of global drawing creation and tolerance analysis.
