(OP)
Should you apply the law of significant figures to GD&T?

RE: significant figures

cmwatson78 In what respect?

ASME Y14.5M-1994 (assuming that's the standard you work to) talks about leading & trailing 0s in section 2.3.  It differs for metric and inch systems.

RE: significant figures

Also, in engineering, rounding is always to the even number to account for accumulation.

RE: significant figures

No, there is no appliation of sig figs in GD&T.
i.e. 2.0 - 1.500001 = 0.499999

Also, there is no "influence" of sig figs on GD&T tolerance.  GD&T callouts are explicit.
