I'm fully aware of this and that's why I'm making my maps without a lot of information. I plan on going back and making changes so right now I'm building an overall library of CAD drawings that can be edited easily in the future :) But I'm also not taking a lot of suggestions as to what should be added to my maps because everybody keeps saying the same things and they all will be the things most likely (or almost definitely) to change. I'd rather have a map with no measurements than a map with completely insanely utterly wrong measurements.
