Hello
I have a plan in which I have tolerated dimensions,
For example: 5 inches with +3 tolerance
The dimensions are in inches and below is the general tolerance.
I'm looking for an explanation, is it +0.3, +0.003 or +0.003?
Thank you.
Hello and welcome Gaitbenhamouda,
If your odds are inches and tolerance too.
So yes, it's +3 it's inches in your example => 5 inches with a tolerance +3 inches.
Good luck.

Hello AR and thank you for your answer,
Does it make sense to have a dimension of 5'' with a tolerance of 3'', plus there are other dimensions for example 0.375'' with a tolerance of 3''?

Well for me when it's in inches it's in inches...

It happens that companies are not clear on this with tolerance smaller than the coast but in theory it is actually in inch, in reality only the person who (badly?) made the plan can affirm it.

±3" tolerance on 5" seems a lot to me. Unless it's an adaptive join.
Could we see a little more of this plan? or at least some ratings to help read the rating.

After that, I've already had 0.5 rays tolerance +/- 1 ... convenient to avoid machining

That's how you end up with products made in PRC that don't fit together with the EU gear

But, don't you have an image capture to show us of your tolerance 5 +/-3?
Because you're talking to us about
which would mean an angle of 5 seconds +/-3 minutes (even more inconsistent ^^)
In short, a direct reading of the map can help answer you

@coin37coin Given the character behind the apostrophe, I think it's a typo, that he wanted to type 2 apostrophes to write inches. This formats the text with arrows.

For me, a +3 rating is to be interpreted 0/+3. Note that in a drawing, a tolerance applied to a particular dimension cancels the general tolerance and only applies to this dimension (of course). In this case, everything is in inches (plane dimensions + general tolerance) otherwise we can't get out of it.
In the case of 5"0/+3 this may possibly be an accepted overlength, why not!!

Re bonjour gaithbenhamouda,
Here's what might help you =>

I saw the plan and it's
3.000 +5
.375 +3
A ±2
B ±3
C +10
…
Since not all values below 0 show zero, I thought that the tolerances could actually be ±0.3, and +1.0 but 0.375 ±0.3 would not make much sense.

Hello again Maclane,
No, no indication of " Standard ".
