Hi.
I have been reading a lot on here, but finally found something I can't find an answer to. I hope someone could help me out please.
I'm trying to work out the correct way to dimension a pair of studs. I've attached an image of what we need to achieve. Hopefully it makes what I'm about to explain easier.
The left hand stud in the picture needs to be controlled from the intersection with the surface [A] up to 5mm from that surface with a tolerance of 0.5mm. Now in the past I've seen it done with a tolerance like:-
[TP][0.5][(P) 5.0][A]
IE a projected tolerance, but I believe this is only for checking "off" the part? Like past the studs end? Would it be prudent to just have a standard callout of [TP][0.5][A] and then a not saying "First 5mm from [A]" ?
This I'm unsure of.
The second one, (it is actually the same stud, needs 2 tolerances) it to be checked ONLY at 15mm from [A] to a tolerance of 1mm. I'm thinking it should be like:-
[TP][1.0][A] and a note "Measured at 15mm from [A]" or, put a boxed 15mm dimension line on the stud and TP pointing to the stud at that line?
Is this right? Are there other symbols or terminology that I am missing?
Hopefully I've explained it right, and any help is appreciated.
Thanks.
Ross.
