You have a great series of marvelous GD&T examples. Thanks for your outstanding teaching skills on the datum shift concepts. Datums simulate the most vital elements of the GD&T language. T J (Tom) Vanderloop, Author, Technology Instructor & ATEA, AWS, & SME Leader & Membership/Leader
Excellent tip as usual. Datum Shift is a great option with flexible design. Thanks! T J (Tom Vanderloop, Author, Technology Instructor, & AWS - SME Memberships-leader
No. Still not clear. Okay, maybe not “bonus”. Maybe we’re getting hung up on that word. But it is an allowance, no? As Datum Feature C opens up, the profile has more room to be, no?
Especially for more complicated cases of shift (2D or 3D) there is a difference between enlarging a tolerance zone and shifting a tolerance zone. Does this take a step towards being more clear?
Hi, I am one of subscriber of your video, I have learnt a lot from your videos, I have one query, how do we prove in fixture that relation we have developed for dia 27mm with respect to datums is correct, we dont have feature for 27mm in fixture or gauge?
umm.... I am not good at writing in english. sorry.. so what size is allowable tolerance zone in positional tolerance? and when I consider datum mmc in positional tolerance? I am confused..
The position tolerance values do not change when MMB is used on the datums. In the example shown, the DIA 27 has a position tolerance of DIA 0.3. This value does not change because datum C is referenced at MMB. Similarly for the 10 slot, the position tolerance value of 0.05 does not change.

How do we know? Because...math. And GDT rules! Great video :)
Thanks Guy - glad you enjoyed the video.
