Geometric Dimensioning and Tolerancing

Interpretation and application

In the course Geometric Dimensioning and Tolerancing (GD&T) you will learn the most important methods of dimensioning and geometric tolerancing according to the latest ISO standards.Are you able to define or interpret correctly the tolerance requirements of a workpiece regarding function, manufacturability, measurability and costs?
In the course Geometric Dimensioning and Tolerancing (GD&T) you will learn the most important methods of dimensioning and geometric tolerancing according to the latest ISO standards.
Based on examples and exercises, you will learn to interpret and define the geometric requirements according to these standards. This course also provides an introduction to Model Based Definition (MDB) in preparation for the transition from 2D to 3D. After this course you fully understand the logic of geometric specifying and you will be able to avoid tolerance mistakes and fully capture complex requirements.


Course Objective
  • To be able to apply form and position tolerance functionally in the formulation of product specifications and while making drawings.
  • To be able to interpret form and position tolerance correctly.
Target group

Constructors and technical draughtsmen, planning engineers and craftsmen, as well as metrological workers. The best result is achieved if the course is organised in-company with these various target groups represented!

Entry Level

Secondary Professional with work experience, Higher Professional.


Three day sessions, each from 9.00 till 16.30r, once a week.

Certificate of Participation

On completion of the course each participant will receive a Certificate of Participation
