Geometric dimensioning and tolerancing (GD&T) complements traditional dimensional tolerancing by letting you control 14 different geometric characteristics. It applies tolerances to the form of features, instead of just to their dimensions.
This videos covers the different geometric characteristics and other key aspects of GD&T including datums, material modifiers (MMC, LMC and RFS), the Envelope Principle (also called GD&T Rule #1), and the Independency Principle.

I genuinely, no joke, don't think I could do Mechanical Engineering at university if it wasn't for this channel and I just want to thank you for everything you've done and everything you continue to do. You will never understand how appreciated you are and I have told and will continue to tell fellow engineering students how awesome and fun you can make engineering to learn compared to the lecturers I'm stuck with. Thank you so much.

This is, without a doubt, the best educational and well-made video I have ever seen about GD&T! I have been studying Mechanical Engineering for many years now and always had a hard time wrapping my head around some of these concepts still, the way you lay it out in the video is super intuitive! You also have absolutely fantastic animations, they are so clear, and precise and show accurately what is needed to get the point across. This is absolutely invaluable to anyone starting out with this! Thank you so much for all the time and effort you put into this!

This must be one of the best videos explaining GD&T. I started my career on a drafting board and then moved our company onto CAD in the late 80s' and it was a long time before ANSI Y14.5 creeped in and was finally adapted on new designs. We still had a long road a head to train everyone down stream on what these funny looking symbols meant. If we had something like this video way back then it would have been incredibly powerful. Well done. Absolutely love the clarity of the details and colors used to illustrate, the pace and smoothness of the presentation is excellent.

@Kelvin_Foo Жыл бұрын

This is one of the clearest description of GD&T I've seen. Explains tolerance zones and geometry control tools pretty well. When trying to explain these to new engineers, I tend to use various shapes of pasta, or GD & spaghetti. Every time I saw a drawing with circularity or concentricity, it was because the part designer really wanted position instead. In any case, I heard the concentricity tool has been removed from the 2018 update of Y14.5.

I’m an apprentice engineer, just coming up on finishing my first year at the company I’m working for, and the other day a guy who works in design (a CAD expert) was helping me with some simple tolerancing, and said “you wait until you have to learn geometric tolerancing.” When I see him next, I don’t doubt I’ll be able to have a decent conversation with him about it, and this video has, at the absolute least, given me a massive step up on the other apprentices when it comes to CAD.

I'm a metrology engineer and this hits every major piece of GD&T that an engineer should know. Great work! I'd like to add that in practice, circular runout can list concentricity, circularity (when the datum feature applies as such), and co-axiality (as off-angle holes will very likely produce bad runout measurements).
