My drawings are the final fabrication drawings for the millwork shops, so any revisions have to be complete through the set, only in very rare cases do I not carry the changes through the entire set. If not done, it is too likely it will not be built right.
If they are changes, they have to be paid for, I don't care if the original documents I was given are 5% or the twelfth revision after issue, once you hand off construction documents to me, any change is a change from my original information. I very rarely get any issues over this, but I don't tend to do repeat work for those who think it should be free because it was issue for bid and not for construction.
