Gerver vs. ODB++ in case of there's some Impedance control line | 3 April, 2009

I've heard from my company's engineer that it'll be better to use Gerber format if there's some impedance control line . Because usually Gerber has code numbers in data and someone can easily refer to controlled line on the PCB and ODB++ doesn't have something to refer.

But I can't trust him. I think that is same thing about both of them. We need to refer to drawings if we want to find some line. In Gerber, it is described by D-code (code number), In ODB++, I don't know what it is, but maybe there's something.

Would you please tell me whether our engineer was true. If wrong, please tell me the true thing.
