“I've been a designer for 3 years, mostly working with CAD and calculations, but when it comes to creating drawings, gd&t has always been a pain. I tried to learn from friends and colleagues, but I always immediately got the impression that this subject is really difficult and I can't learn it. There were always discussions and disagreements about what the symbols meant. If you look at the books and reference books on the subject, they like to make things more complicated than they really are, don't they? This course just gets to the point, the instructor is knowledgeable, the explanations are very clear and the course project is very engaging. I look forward to more courses from you”


“This course is for every designer who wants to push his career forward. outstanding experience. I am waiting for more courses from you.”


“So far I am really enjoying the course. The video is professionally made and the instructor is very clear. I am looking forward to the rest of the course.”
