I am putting in a 12 mm hole and trying to give it a "standard" tolerance
It is to be a G6 toelrance.
Everything I find online says the G7 tolerance is +.017/+.006
In SW, it is +.020/+.008
This does not bode well for my engineered fit!!!
i believe i found the culprit.
it was on "user defined", rather than press/transitional/clearance.
I did not modify the tolerance per se, but it pulled wonky numbers from somewhere
thanks for the assist
I am getting +.017/+.006:
I am not sure why you aren't
Is it possible that you have accidentally overridden the tolerance?
I see same thing as what Dan showing in his post
Seems like it's a user defined number
Glenn: can you create a new dwg and check the G6 tolerance from FM?
I have not manually altered them, and if i toggle between various G tolerances, the numbers do change, but they are not correct. I can find anything in settings to change this. :/
Funny ... I don't even get the dialog box you get Dan. Odd to say the least. Oh, and my tolerances are wrong too ..
Maybe it is because of the difference between SW 2015 (which I am on) and SW 2016 (which it looks like you are on).
And your tolerances are correct:
Glenn's hole was 12 mm hole, which falls into the column with the red arrow.
Yours is a 6.5 mm hole (approx.) which falls into the column with the dark blue arrow. The numbers in the boxes are in thousandths of a millimeter (+14 = .014mm), AKA, micrometer or micron.
Here something I just noticed regarding tolerances.
Using the Fits while making a drawings is fine, it does match the ISO chart.
However, the same FIT in DimXpert differs.
For a 50mm bore, I get +0.025 mm / -0 mm (+0.001" / -0") (in a .slddrw)
When using Dimxpert for the same part, I get +0.0008" / -0" (approx 0.020 mm vs 0.025 mm)
The Excel general tolerances file doesn't have min or max.. I still didn't figure how to have both drawings and Dimxpert tolerances to be the same... Its not much, but standard means to be standard.
Any ideas !?
Found the issue. The small chamfer is changing how the tolerance is defined. Dont ask why, this is not normal. I removed the chamfer and now the tolerance is showing as it should be.
I tested a new freshly created part and I wasn't having this issue... I figured out there was something with the other cad model.
Case closed for me!
Why do you say you need a G6 tolerance and then complain that the G7 tolerance doesn't match G6?
it was a typo, but thank you for your valuable input
That's what I was confused about as well....
well, the tolerance was not correct for a G6 either.
picking nits instead of analyzing the issue
Not "picking nits". Sometimes smart people say or do dumb things. Like you just did again.
good day, sir
i am surprised the mods let people troll here
Seriously, Glenn, LTFU. I pointed out the typo because sometimes people make tiny errors that lead them down the wrong track. It happens. It was meant to be helpful. If your inner child reads everything in the voice of a schoolyard bully that used to give you atomic wedgies, that's your issue, not mine.
