What is the differences between ASME Y14.5M and ISO 1011 ???
(OP)
As I know, ASME Y14.5M-1994 is a complete GD&T Spec., but ISO's GD&T is splited into many ISO specifications.
Is any boby tell/provide me the whole ISO specification NO., which related to GD&T? And What are the differences between these two GD&T specifations? Or where I can find the answer.

Not sure specifically on just the iso series.

Unless you really need the ISO spec, for foreign contracts,forget it and use ASME. It has some significant differences anyway, such as interpretation of the envelope principle that Y14.5 calls Rule #1, ΒΆ 2.7.1.

I was told that ISO allows datums on centrelines, but I have not seen an explanation of how they do it. I just assumed that there was some mathematically rigorous way to figure out which round feature the centreline belongs to.
Is it that much more complicated?
