I would think the only way you could do it would be to explode the field after rev 1 is sent out.. Maybe there's something you can do with an attribute block and assign a field to it. Hmmm.. In my dimented little world, we don't track revisions but, I DO have my dates as a field so when it's plotted I can see what date the drawing was plotted on. Much better than the old plot stamps, that's for sure..
