Heather attended a three-day ISO GD&T course in May 2022 led by Dave Masson MIMechE, a design engineer who has decades of experience in industry. The course took place in-person at the IMechE’s London HQ, with 11 other students (making it a full class).
Heather explains that the first day was theoretical, introducing “how the standard works, and how utterly bonkers it can seem at first!” She learnt about GD&T’s terminology and the logic behind its pictorial symbols.
On days two and three, the students delved into the language in more depth. They learnt about the data and references, specific GD&T symbols, and how to use them on a drawing to build up a tolerance framework.
Besides the course content, Heather says she particularly enjoyed the teaching. Course tutor Dave Masson had “spent so long in industry at so many different companies with so many different products; he really does know the subject” she says. This meant that the sometimes-abstract concepts covered in the course could be illustrated with real world examples that brought the ideas to life.
Heather adds that the course training aids were useful too: “we were passing all sorts of different components around, and you could look at them while he was talking to you and get a handle on it”.
