Hello Dr. Swanbom, I have been watching your videos for 3 days now and I can't say enough how your lectures are helping me brush over my concepts from years ago.

Really liked the way you combine all important concepts into a video! You videos are treasure for mechanical engineers! I am following all your lectures !

Thank you so much for this. I have been looking for someone who has a throw and detailed explanation. Just this video alone puts you at the top of my recommendation list on this topic

Thank you for putting online these intelligent and crystal clear lectures. It’s obvious that you have a very good grasp of the topics that you teach, but what’s even better is your ability to communicate that understanding in such a concise and that-makes-sense manner.

Michael, when you were discussing how pipe sizes were nominal sizes rather than actual sizes, you mentioned another name that you couldn't recall at the time. I suspect that you may have been thinking of *tubing* at that point -- where (round) tubes *are* sized by their actual dimensions unlike pipes. This one threw me at first when I was a newly graduated ME, but it didn't take long to remember their differences in sizing (back in the stone-age). Thank you for sharing this short playlist of GD&T videos!

I moved to Louisiana (from Virginia) back in 2012-2014. Loved the state, met a couple of La Tech engineers. Top notch people.

Over the years, I've studied numerous video compilations devoted to GD&T but always gravitate back to the TheBom_PE series. Anyone interested in learning GD&T from scratch should watch this video series in order and read Chapter 20 on GD&T in Shigley's Mechanical Engineering Design. I cannot think of a more thorough and comprehensive starting point.

You're the best, these videos are very educational. This is helping a lot. It would be really cool if you did a lab day and measured parts and went over the gauges and tools used in metrology. Or even some CMM stuff.

Finally!! Thanks for explaining this in layman's terms.

Hello Professor, I just wanted to let you know how much I appreciate you uploading these lectures on GD & T. I have been searching for informative GD & T videos for several months now, but non of them are as detailed and well explained as your's. There are a lot of books to learn from but what I feel is when it comes to GD & T, it's best to learn from a professional and I'm really happy that I found you on KZread and that I can finally learn GD & T. Looking forward for all your lectures related to it. Thank you so much!

Nice catch! Yes, I did nudge the speed up just a little tiny bit so that I could fit the whole thing into a 75 minute timeframe.

To help avoid criticism about having a lecture that was too long, I just made a little edit :)
