Whenever I open an assembly in Solidworks, I see messages telling me that things have changed, and asking me whether I want to rebuild the assembly.
This happens even when I have just started Solidworks from cold, and just fetched the assembly from the PDM Vault.
Why does Solidworks think that there have been changes, even though, as far as I can see, there haven't?
It's not a big deal to click away the messages, but I would like to understand what the message means.
