I've recently moved to Inventor 2010 and I've migrated our custom CC libraries which I think worked fine. The data is there and useable, the only problem is that when I add a new property value, that value doesn't show up when I pull the part from CC. It's as if the library is somehow in a read only state even though it takes my changes. I suspect I'm over looking something or screwed something up in the migration. It worked fine when I created the libraries in 2009. Anyone have any idea's?
