I just want to state the fact that he is not explaining what GD&T is, but rather why it's useful. He doesn't explain anything about how it works, what the symbols mean, how to use true positioning, etc... My hat doesn't come off that easy
@@xz3693 Read the video title. Key word: "What". Not "How" is nowhere in the title. Lord have mercy people never read instructions anymore do they......the man did exactly what the title says..smh
You are meant to be an educator man! I love how you explain from zero without assuming we know anything which is always comfortable to brush off things we know and build on it with new information.
Hey there Cillessen Built! Thanks for the positive feedback! I plan on continuing and I think my next video will start to cover GD&T Symbology. Here at Straight To The Point Engineering we are all waiting to see the next project from the Cillessen Built design/fabrication/construction studio as well! Stay safe and healthy!
@@StraightToThePointEngineering do you have any classes online I really love the way you explain things I'm very very new at this so I don't know all the terminology yet I wonder if you have a DVD or anything I would buy it I think you're amazing In explaining it.
Thanks so much for this straight forward video, aspiring solidworks designer currently in school studying GD&T! I will keep coming back to this channel for info, keep it up!
Hi James Barnes! Thanks for watching and for the friendly uplifting comment! Download the drawing PDF from the description and let me know what you think (I also included a 3D PDF this time in case anyone is familiar with those)! Thanks again for watching and stay safe and healthy!
@@StraightToThePointEngineering love that the drawing PDF is super clean and could easily be done by hand check as well as cmm. Basic yet explains everything you need to know to make a true part.
Good video on second part. But very misleading at first. Regular dimensioning has been used for a long time. To say that you cant use it and not guarantee your assemblies wont work is wrong. Just like anything, if done properly it will work just fine. Been using it for 35 years building many complex tools, and our company has been using it for 63 years no problem. Not saying this is not good or doesnt go farther, but how did we get by up until it arrived.
Hey there AB Carlson! Thanks for the positive feedback and kind words! It's a lot of work but I'm really enjoying figuring out the best way to present the information in a way that doesn't waste anyone's time! Thanks for watching and again, thank you for the kind words!
I’m a retired mechanical engineering manager. We did not have assembly problems with the classical tolerance system. Converted to GD&T because that was the way the wind was blowing. Led to endless ‘discussions’ among the designers and burned through hours trying to figure it out. (And we had GD&T classes). On balance, it was a loser for our (mainly cylindrical) parts and assemblies. Use GD&T where needed, where NEEDED. I think a thesaurus of GD&T assemblies and parts might be useful as a reference.
Hi again there Dante! I appreciate the love man! Be in the lookout soon, I'm working on the next one! Thanks for watching and for taking the time to post a positive comment! Stay safe and healthy!
Great Video. I think one thing that I would have added to point 6, is that its important that all people involved WANT to use GDnT, instead of traditional methods of tolerancing. Also its worth noting that the trade off in using GDnT is more time spent interpreting drawings at every level. Once you have your head around the system its really not an issue though
This video on RU-vid is truly awesome. CAD/CNC/CMM imply to design, shop-floor manufacturing and quality control (QC) inspection/open setups or digital verifications. Thanks for a great 10 Minute video. We have a number of students at the Chippewa Valley Technical College review this (Albuquerque-New Mexico) training video (RU-vid).

thank you! i was so confused with gd&t since i'm using it a lot in my school for projects, now i understand the basics! amazing video, you deserve a million likes more :D
Very Nice, however, how are the parts made? Is the clearance "0.005" or "0.001" between parts. How is the temperature coefficient effect this design? Does GD&T include temp as a parameter or is this separate.
This guy is amazing, he makes GD&T look way simpler. Not to mention his amazing teaching skills. Hope he returns soon to making videos. Congrats on your great content Mr. STTD
The intro explaning the essence of geometric function is great: Only in the contex of an assembly a function is realized. But no one is bothered by the lack of an explicit functional specification. I'm afraid so it can't be surprising that the presented gd&t of a single part has errors: E.g. datum B and C are equal? Take care for the function: Every real feature of a datum has a toleance itself. This must be taken into account when calculating the calling geometric toleances! By the way one last question: What are the mainfunctions of a geometric feature? It would be very helpful to clearify this first.
GD&T is "Geometric Dimensioning and Tolerancing" Geometric dimensioning and tolerancing provides a comprehensive system for symbolically defining the geometrical tolerance zone within which features must be contained. It provides an accurate transmission of design specifications among the three primary users of engineering drawings; design, manufacturing, and quality assurance groups. Some techniques introduced in ANSI/ASME Y14.5M have been accepted by ISO. These techniques include projected tolerance zone, the three-plane datum concept, total runout tolerance, multiple datums, and datum targets. Although Y14.5M follows ISO practice closely, there are still differences between ISO and U.S. practice.
i've got an offer to apply for a manufacturing intern position and one of the requiirments is being familiar with gd&t. I majored in psychology after switching from computer science. I've always had an interest in mechanical things and have fabricated race car parts on my own. even though I have no formal education or experience in manufacturing/engineering should I still apply?
GD&T newb here. Best GD&T intro video I found so far. The way you explained mating surfaces as interfaces clarified for me what datums are and how they are used. You got my sub. I'll be watching more.
I got some background on GD&T but needed to get to very didactic material that helped me to refresh my knowledge and these videos really get straight to the point. Thank you guys.
Either YT is bad at searching, or you have bad tags. I searched advanced "GD&T for CMM position" and this came up. Seems like this video is meant for a GD&T-denier or something. GD&T can be explained in 30 seconds. Extra info on production parts... Easy.
Hey, based on the amount of positive support you tend to get on these videos, people would totally financially support this endeavor if you made a Patreon. Just a thought. This is content that a lot of people would pay good money for.
Hey Trent! Thank you for the suggestion! I've seen Patreon used by several channels that I'm subscribed to and I've thought about looking into it. With your comment though I'll think I'll give it a bit more attention! Thanks again!
@@StraightToThePointEngineering i would definitely support you if you decide to make a patreon, this is grade A quality content for engineers, my only request would be to upload more regularly please
@Mario Jacobo I appreciate your support. I know you always watch my videos and always provide such great, supportive comments. I will definitely look into the Patreon option. FYI, I am planning on giving this channel a lot more attention and make my content uploads a lot more regular. I think I can make something of this channel if I dedicate myself to it and make sure I engage people such as yourself who are so supportive! Again, thank you!

thank you so much for this amazing video .. i have already finished one drawing in AutoCAD with GD&T BUT I WANT SOME CHANGES .. please can you provide me with your mail to check it .. thanks in advance
How to overcome the issue is that not everyone knows about the "system" and are capable of reading and understanding how to use and apply it. What is the strategy for overcoming this? I have always felt that this topic is not covered well at all in any technical/engineering school.
Hello I would like to thank you for your video are very informative. I have a question about the tolerance's numbers. For example all these symbols and letters are understandable for me but how someone will take the decision for the size of the tolerances or what is the suitable tolerance for him? ok for the bearing or o rings etc you can find specific tolerances tables... But when you have to take a decision for example... to fit a rectangle to a pocket, how can you know What size (tolerance) should have your rectangle? I can think a few questions as a gui to help me to decide, like do I have a thermal expansion? For what use do I need the assembling etc.... Is any book can help me? Thank you
Your doing really well, so why don't you make series video content of gdt for new people it will simplify the way for who want to learn gd&t in very deep, thank you.
This was an excellent explanation of WHY GD&T, but it utterly failed to fulfill the title of the video: WHAT IS GD&T. What you explained, you explained well. But thumbs down on this video because you didn't do what you said you were going to do. I watched the entire video waiting around for you to explain the WHAT while you only explained the WHY.
Hi Steve Gergetz! Thanks for watching all the way through. I suggest watching the video starting at 3:00/10:08 . This begins the What IS GD&T portion. Thanks again for watching!
Welcome back sir Thanks for new video . I have doubt related to coaxiality . Please make video about that How to measure coaxiality b/n 2 bushes 400mm apart . (Lwr arm part coaxiality)
