i recently got denied of a job because i didnt know how to read GD&T or blue print reading. i was asked about how i would go about this certain part and how i would machine it and the overall size etc i also didnt know what the symbols meant. i been looking all over the web for gd&t and its hard to find a course that is easy for me to learn from. i ran into your channel and your instructions are really good and i can understand it for the most part. do you have a video that can help me? do you have a video that goes over all the symbols and what do they do? gd&t for dummies. please help. im willing to pay for courses if you have some online. thank you
