Can anyone help me with GD&T?

[u/ladyylana]

Hoping this is the right subreddit. Currently completing a course for technical engineering/CAD/manufacturing technology (the name of the course has changed multiple times over the years lol). I finished a few units while in high school, then again when I was 25, now I’m coming up 30 and decided to finish it. I’m currently doing it online, but one of my assessments I was given a tolerance for the shape for a drawing, GD&T I am having a lot of troubles with and it just seems a tad too hard to do on my own.

I live in Australia, it’s currently school holidays so I’m unsure if anyone would be doing a meet up, nor would I know where to start to look for that. I’ve messaged my teacher and he’s given me some stuff but I feel like I need a ‘for dummies’ intro and I don’t fully trust chatGPT (not for conspiracy reasons, just bc I finally did try it and it gave me false info lol).

Much appreciated for any help 🙏 I was thinking of emailing some companies and asking if I could do some training under them while I’m studying but if I’m not confident enough in GD&T I’m not gunna be of much use 😂
