Training content

Ten modules in one day

The training covers the specification side of ISO GPS: how requirements are stated unambiguously on the drawing. Teaching from 08:30 to 16:30, with breaks and time for questions. Each module shows an excerpt from the training material. The animation in the middle of the screen plays by itself as you scroll, only one at a time. Click to pause it or to start another. The training material is in German, the language of the training.

Foundation and depth

First the basics, then your drawings

The basic training gives your team a common language. Anyone who then wants to work on their own drawings goes deeper in the ISO GPS workshop.

Basic training
The fundamentals of ISO GPS specification in ten modules, in one day.
ISO GPS workshop
In-depth work on your real drawings and parts, in small groups at your site.
