Dean Odell is a great instructor with the "Basic Geometric Tolerancing Standard" with ASME Y14.5-2018. Keep up the excellent "TH-cam" graphic slides as it is all about the visual design intent. Thank you and I hope we can visit in the future and "Talk-Shop" on "GD&T" applications. Enjoy the educational experience! T J (Tom) Vanderloop, Author & Technology Educator
This is really helpful. I'm kind of disappointed they changed the symbolism for unilateral tolerance, but I really don't see it that often on drawings anyway. Calypso can report equal bilateral surface profile as two results - a min and a max value. They're displayed as positive and/or negative values, whereas the single result only displays positive values, so I feel like the 2 results give more information. My machinists are confused by this reporting, though, so I've tried to figure it out with them. My current theory, and this video solidifies it, is that a positive value is a point on an external feature that would add material to the part, and a negative value is a point on the surface that would take away material.
Fantastic video. This tolerance type is useful when you really want to use a non-symmetric size tolerance on a non-feature of size. Except for no one knows what the U is and inspectors hate profiles. Maybe using the U and the dotted line is the way to go?
Hi, yeah I know the U symbol can be mysterious. I don’t think it would break any rules to show the phantom line with the U symbol if it helps with readability. I’d make a note somewhere explaining it.
Hi, the left side is always the total tolerance. The number on the right indicates the amount of the total tolerance that applies in the direction that would “add material”.
Hi Sir , Can you please make one video on measuring profile of a surface with Datum A,B and C reference? This will be really helpful. Share your screen also to understand calculation and alignment

Great to hear from you again! I’m always working on new ways to present the material.
Very clear explanation, it fades away the tricky issues.
Thank you!
Thank you for your detail explanation. It was easy to understand . 👍

Great, thanks Dean! Hey, does any of your vids explain the Independency symbol?
Nice video ... congratulations from Mexico
Hi, thanks for the support!

Great work. Would like to see example where surface “bonus” tolerance is changed by MMC on both B hole and C slot.
Thanks so much! I’m working on some content addresses the various uses of bonus tolerances.
Hai Dean Odell
How can we consider if right side tolerance of U is greater than left side of U.
Hi, the left side is always the total tolerance. The number on the right indicates the amount of the total tolerance that applies in the direction that would “add material”.
Could you please explain how the tolerance is reported out in terms of max min deviation. ISO is max point or devotion x2,how does ASME differ?
At 3:41 you subtract .05 from the .750. Wouldn't you subtract the .05 twice? Once for each side? The smallest hole is now Ø.650?
