Revisions - driven by part or by drawing?

[threnody]

Hi,

Parts, assemblies and drawings all have a revision property that you can map into a drawing title box.

My question is this: which of these should drive the revision number on the drawing?

- If you make a design change to the part or assembly, this triggers a revision. This is (or seems to be) obvious.

- If you correct a drawing error, or make an addition to a drawing, this also can/should trigger a revision change, even though the part itself has not physically changed. If your revision number is driven by the part, you would need to manually bump the part revision to change the drawing. This seems wrong.

Any thoughts?

Regards,

Paul

Hello, great question.

This is one of those that does not have a "right" answer.  The correct way to manage your revisions is the one that works best for you and your company.  In my experience, a revision level change was always defined as one that affected "form fit or function" of the part or assembly depicted.  So, for example, a text change or spelling correction would NOT affect revision, but a change to the part or to notes on the drawing that affected its production, would.  

At my last company, we controlled the revision on the drawing file and not the parts.  The reason was that the equipment we built was mainly piping and valves etc, so when we made a change, it affected the overall assembly and not one specific part.  That's what made sense for us.  I feel like I'm not getting you anywhere, but it really comes down to what makes the most sense for what you are making.  Once you decide on the path that makes the best sense, there are ways to set up your Revision Schemes, Lifecycle Definitions, or even use ECO's to implement your plan.

Chris,

Thanks for the reply. I appreciate this is one of those "how long's a piece of string?" type questions with no definitive right or wrong answer. I'm just looking to get a feel for what others are doing.

Oh, for sure.... I'm hoping that you get at least a few more opinions here... I just wanted to get the ball rolling for you.  LOL 😂
