Revision History in MBD Models

[OM_10919029]

Traditionally, our company uses a revision block on 2D drawings to show the current revision and list all changes from the previous version. As we transition to model-based definition (MBD), I'm trying to determine the best way to display revision history directly within the 3D model.

My first thought would be to use a table similar to what we do in 2D drawings; however, I am currently using Creo 7.0.2.0, and editable tables are not added until Creo 11 from what I've seen. My second thought would be to have separate combined states for each revision displaying everything that has changed, but if a change is made to a dimension that is not initially displayed in the model, such as basic dimensions, how should that be documented for approval purposes? Another thought would be to use "Is/Was" reports, but this seems to be tedious, and I had the same question about what to do with dimensions that are not initially displayed.

Would anyone who has experience with this be able to weigh in on the best way to proceed? I'm looking for best practices that make it easier for quality, manufacturing, and analysis teams to review and approve changes directly from the model/3D pdf.

One of the important aspects of MBD is to consider carefully the information that is included in the model.  Assuming you have a PDM or PLM like Windchill that tracks the revisions through ECN's, duplicating the revision information in the model provides an opportunity for errors.
Just because you had that information listed on a drawing does not always mean that information needs to be included in a model in MBD.

We still use drawings in many applications, but most of our drawings do not show a BOM, revision history, or approvals as all of that is already in Windchill.

This is just a suggestion based on many MBD presentations I have seen and found on the internet.
