5 SIMPLE STEPS for Geometric Dimensioning & Tolerancing | GD&T EXPLAINED | Serious Engineering: Ep27

[@starrapid]

GD&T, or Geometric Dimensioning and Tolerancing, is a logical system of numbers, symbols and conventions applied to 2D drawings, either electronically or as blueprints. Have you ever used GD&T? What are your thoughts? Leave them in the comments below!

Extremely valuable. I have been a designer in SolidWorks for over 15 years, and was ignorant of how this worked; I knew intuitively about datums by way of design intent, but now I fully understand the basics of GD&T. Thank you for this primer.

Thank you. Comments like yours motivate us to produce more.

Love the fuse & both architecture & engineering with a decimal solid 3dprinting machine!

Damn! the stuff I didn't know I needed to know. Thanks for sharing your knowledge! much appreciated.

[@dodaexploda]

This is really good info. As a hobbyist it's good to know what I should be looking into. I had no idea this existed before now. Thanks!

@@starrapid Well then, I'm happy that I commented. I'm just a hobbyist playing around with a 3d printer, but I've learend so much from watching your videos. So thank you!

Thank you kindly for this!!

You're very welcome!

Thanks for this video, much appreciated.

Thanks for watching :)

Why is IJK used for rotation when xyz is used for linear movement? Is there a logic there or did someone just pick random letters?

[@fadirasmi4403]

Thank you ! I subscribe to the 5 rules. Does this apply to bigger parts, say a frame of a bicycle made of tubes or in composites for instance ? Thank you again.

[@starrapid]

Thanks for the question. Yes, absolutely GD&T discipline applies regardless of part size, product or material type.

if we do not use GDT what would be happened ? your feedback will appreciated .

[@jehanzebawan43]

Nothing. You can use +/- tolerances. It makes inspection and tolerance stack up hard. If your quantities are not too large, you maybe fine

[@mohamadkhatib8624]

@@jehanzebawan43 that means The more assemblies we have the more GDT we need for complex assembly right mr jehanzeb ?

[@lawrencestrickland9264]

@@mohamadkhatib8624 HI by using only +/- dimensioning it is impossible to convey the design intent. In addition you are unable to establish the true relationship between critical to function features in relation to the matting features aka datums. This leads to a ton of manufacturing problems down stream. Like over toleranceing features, which drives up the cost. GD&T is a language and properly applied in addtion to being understood gives back tolerance to manufacturing. They what a machinist wants to hear.

@@lawrencestrickland9264 sounds great mr lawence we really should care about the function and relation between different feature .its great to have your update

I completely disagree that you generally only need 3 Datums. You did qualify your statement by saying "3 is enough for everything you have worked on." I work with all the world leaders in manufacturing and %80 of the drawings i work on have more than 3 datums. I believe that is a reckless statement. You are going to get some new inspector or machinist yelled at when they say that to a good engineer.

[@rinnengan71]

"These 3 are usually enough"... I understand why most people say that engineers have little to no reading or listening comprehension.
