Hello to all,
This is my first post here! I wanted to start off by thanking the community for this chance to discuss a few topics that has come up a few times already.
So I have been designing for 17 years now in the fields of Mechanical machine parts and assemblies, MEP, and Architecture disciplines. Just recently the company which I have been with of going on 5 yrs, has been looking at setting up standards for ECO process and revising drawings. We had a large debate on when to revise or create a new P/N for changing parts. I have always worked off the three "F"'s. To my surprise, ANSI does not follow that. My question is "how was I misled this whole time or did the standard change when ASME and ANSI combined?
All of my experience says to revise a drawing if there is a change to the Form, Fit, or Function of a given part. ANSI states if a part is not backward compatible then is gets a new part number not a new revision.
What are the thoughts of this community?
