There is a utility that was designed to raise the version of large quantity of Cimatron catalog parts. It will also work on regular parts and assemblies because it is really just a macro to quickly open and re-save.
You must add a special flag (-Updatecatalog) to the Cimatron startup. Go to the properties of the Cimatron desktop shortcut and add it at the far right end of the target line.
This will add 2 new functions to the Catalog Menu. Update Catalog and Update Catalog Geometry. The functions are about the same, but Update Catalog cannot do assembly files.
