Thanks to everyone who responded but especially to Greg. I would like very much to have a 5 minute conversation with you but in the meantime I'll say your answer sounds like the best solution. At the risk of sounding like an idiot I'll just state what I think would work best for us and if this is what you're doing now and/or can be done "fairly" out of the box.
So essentially as you've suggested we blow out the bom and rev history stuff out of drawings and let WC, in this case WTpart within WC, do the work and push the info inputed within WC down to the final drawing by way of a superimposed image on a blank designated spot on the pro/e drawing where the bom and/or rev history block used to be??? If that's the case sounds awesome!
Furthermore, we could magically have multiple pdf drawings, ones with this info, and others without, etc...???
Maybe superimposing wasn't what you were suggesting and instead attaching this info a secondary sheet in the pdf or something? Like I said, would like very much to have a 5 minute (okay, who am i kidding, a 5 hour conversation with you)... :-) Thanks.
