it is very strange, but strange and bizarre seems to be normal for Creo.
Nope, no saved searches.
This change happened as I opened the assembly this morning.
Colors had also changed on several other components.
A change in color I can live with (but WHY???). A strange highlight in the model tree fills me with wonder and doubt.
Computer is turned off at the end of each day. No one was here this weekend to modify and even if they had been here, wouldn't have been messing about with my project.
I know believe Creo does some things really well, (else I'd have to think that everyone who pays for it is crazy and I don't think that. )
However, I have yet to discover what.
