I know this may seem like an odd question... but it might come into play. In the earlier days (pre-MBD) it was the original drawing/drawing representation that we were updating. Now with MBD, we will be publishing a *new* PDF every time. Granted it will be based on the same model each time, but the PDF will be new.
With this in mind... what will you be doing for: (keeping in mind that with MBD, the MODEL is the master)
signatures - re-sign every change? Or hard code in custom properties?
revision history - list on the PDF? Maintained in the model some way? Or just keep past revisions in your vaulting system?
I am looking forward to the discussion.
