Diagram Retirement
As you all know Pro/Diagram is being superseded by Creo Schematics. In Creo 4.0 we are restricting access to Pro/Diagram via a hidden configuration option and in Creo 5.0 we will officially retire Pro/Diagram turning it off completely.
To turn Pro/Diagram back on you need to add enable_obsolete_modes True to your configuration file and start Creo.
