Check out TPI 132326 "PTC has created a Granite plug-in module to replace the neutral file approach to cross-release interoperability in Pro/ENGINEER Wildfire 3.0. This plug-in module can be provided to a Wildfire 2.0 user and, when installed in the Wildfire 2.0 loadpoint, will allow that Wildfire 2.0 user to read the Wildfire 3.0 model directly via Granite. This is without the need for the Wildfire 3.0 user to create an intermediate neutral file. All of the information that can be read from the Pro/ENGINEER model by the Granite kernel can now be leveraged by the Wildfire 2.0 user." Regards
