geometric tolerences
(OP)
hi,
i 've seen in one german drawing that represents GT.
They 've given in first frame flatness symbol, next frame 0,5 value and third frame 105,0 like this.
in generally we r using GT as first frame symbol, second frame tolerence value, 3rd frame it's reference plane.
that's why i want to know , what they mean to represent the above GT. is there any diff types to represent the GT? instead of ref plane , they 've given 105,0 value. what is the exact meaning of this value?
the total len and width of the flat surface is 250mm and 163 mm.
thank u,

I just took a look at my copy of ASME Y14.5M-1994, and I see no reference to anything other than a flatness symbol and a tolerance. A third number has no place in the ANSI/ASME GD&T system.
It is very likely that your German colleague is using the ISO GD&T standard, which may allow this. I do not know what the ISO standard is, and I have not seen any techanical articles on it. I think yuu are completely justified in asking him about this.
