Thanks!!

Okay. Last question then (sorry). There is gen. tol. (±0.5mm)on drawing for all Feature of size. Would this stud Diam (Ø6 mm) be considered as Feature of size, as shown in drawing?

Ohh! It is actually a threaded stud. How would you recommend gauging this dimension then

Thanks Dave! I guess it makes sense. Another follow-up ques then, if the Stud dia is Ø06±0.5mm and positional tol is 0 at mmc, for gauging, the size of the bush would be 6.5mm on the vertical side and 7.5mm on the horizontal side (because of pg2). Right?

Yes, but they mention STUD in both of these. Not sure, thanks for the help. I am thinking they should have put Perpendicularity for Datum B, but then in the checking fixture it is the same thing since it would be going in a bush.

This customer is used to putting different dimensions on different pages. Eg: Datum callouts on one page, then profile callouts on another.

Hey everyone, I'm working on a new drawing and came across something confusing. Datum A is a plane. Datum B is a stud, which has a positional tolerance on one side (without the Ø symbol). On the next page of the drawing, the same stud is referenced again, but this time with a positional...

Interesting insights! A few points for clarification: When you suggest using the largest surface as the primary datum and defining the secondary datum along the perimeter, wouldn’t trimming variations potentially affect the hole positions? Since adding an extra hole in the large surface isn’t...

ASME Y14.5

Hey everyone, I'm a bit of a novice when it comes to GD&T. I can read drawings and figure out how to design a checking gauge based on the GD&T, but this is my first time being tasked with applying GD&T to a part. My boss has handed me a bracket that attaches to a car and supports the spoiler...

Thanks Guys!!

@3DDave: It is ASME. Let me use different words, Yes, they can be on different surfaces, but they are on different PLANES.

@ctopher: There are just Vehicle co-ordinate system and just shows what datum is restricting what axis i.e. C/C: Cross-car, F/A: Fore-Aft, U/D: Up-Down. For this thread, please ignore these directions for now.

Hey everyone, I’m back with a bit of confusion and hope you can help me out. I'm still learning GD&T, so apologies if this seems like a basic question. I received a component drawing where the primary datums are placed on two different surfaces, and the C datum is on a curved surface. My...

Guys, lets ignore the positional callout for now. Can you guys give your views on the datum scheme. Since the dia. of threaded hole (B & C) is not given, what should we go with
