Whether you are new to GD&T or have a full engineering background, our site provides the most valuable resource for training and reference that you will find anywhere – GD&T Basics
This site is one of my all time favourites for Geometric Dimensioning and Tolerancing. There are loads of clear examples, videos and great diagrams to help explain concepts.
- Diagrams and videos are fantastic
- Worked examples in each topic
- It’s high quality information and it’s free!
- Sometimes isn’t clear on which standard (ISO, ASME, BS etc.) interpretation is being referred to
