I have a drawing that is ASME Y14.5M-1994 which says in the notes that all basic dimension are +/-.010 and on the part edge profile it says .002 shown with the unilateral phantom line. Is that then a composite tolerance?
They shouldn’t say a basic dimension has a plus minus tolerance. That breaks like a bunch of rules in Y14.5. I would interpret the profile at face value, meaning it overrides any other tolerance that may apply.
A lot of people posting video about gd&t like this: ua-cam.com/video/Z-AwrMlEdDY/v-deo.htmlsi=cDU31OkTGDbBebmt The datum A is the flat surface with diameter symbol and also the profile of a surface with diameter symbol .I will never watch random videos again.
Yeah I think that guy is just trying to show how the software works. Putting a diameter symbol in with profile is pretty egregious though. I’d take a guess that that software is clunky and weird, and the diameter symbol is automatically repeated.
@@RDeanOdell Now this is getting confusing. According to Geotol Pro, a datum should represent an axis or plane, with runout being measured in reference to that datum.
@@asaholeyI think I see where the confusion is: the datum comes from the feature, not the geometric control. So the datum is an axis derived from a cylinder, whether it is controlled with position, runout or anything else.
Thank you. It's great to benefit from your information.
Glad it was helpful!

Yet another awesome video! Thanks Dean!
Glad you enjoyed it!
Hello college student here, with regard to the tolerance value in the GD&T (in this instance, Ø0.14) how do you determine that's the value needed?

Sir, plz make video on how to use trigonometry formula in cmm programming
Are online courses available?
Great informative content 👌 thank you!
Glad it was helpful!
Sir,
Can i come and learn under you 🙏🏻
Where did you get the mmc 0.995? 1.5- 0.005 = 1.495
Nice catch xD
I’d guess it’s just a mistake, I’m not trying to rewrite the laws of mathematics or anything
I came across this: ua-cam.com/video/NE7qDGybv5U/v-deo.htmlsi=FM5kf2Cn64RhyQ4c
Is this correct? Assigning datum A with a runout?
Hi, yes it’s legit. I know it’s weird.
