Creo requesting checkout of parts on opening

We use Pro/Intralink to store our cad data and one of the annoyances that comes up all the time is being asked to check out models when opening. It appears to be random components/assembles within the models, but I have to then select from continue, checkout, or mark read only. Each of those presents it's own problems, but I'd like to understand why this happens. Does anyone have any ideas?

Can you attach the parts and assemblies?

Any reference from models to each other other than assembly constraints?

With everything open in Creo and looking at the global reference viewer, any dependencies?

The number 1 reason a file is considered modified when opened is it was last saved in an older version of the software. If you just moved to Creo3 and open an assembly that was last saved in Creo2, you will see that those Creo2 files are considered modified.

All models were generated in the same version of Creo.

Two things to look at/for:

1. Circular references.  In your startup directory are there any *.crc files?  Removal of all circular references will make Check In and regeneration faster.

2. Use the Global Reference Viewer to investigate the references and dependencies.  This includes Relation references.

Hope this helps.

No .crc files exist in my startup directory.

What would I be looking for in terms of dependencies?

Model B is a subassembly of model A in this instance.

If I open up model A, it says that model B is read only and cannot be modified. If I unlock model B, then I have to select checkout, continue, read only before continuing. If I open model B, it asks the same thing and always puts a + at the end of the iteration as if I have changed something in the model. I'm sure it has something to do with my workflow, but I'm not sure what to look for.

Unfortunately I cannot upload any of these components.

Okay, so when I looked at the reference viewer under dependencies I saw several objects with a big X next to the name (they were suppressed objects). I also found one components with a dependency (had a trash can icon next to it). That seems to have fixed it, thanks!

So I guess the next question is - what causes dependencies? I didn't see anything in the model that was referencing the parent assembly,

I usually have to look at those "odd" references to figure out why they came about. I know restructure can cause them. Sometimes they are old references that, for whatever reason, stuck. I'm sure there are some really valid reasons, I'm not smart enough to figure them out tho.
