How do you save a part file to a previous version? ie 4.0 to 3.0

[PhillDavis]

I have some part files I need to exchange with someone else. But the parts are in version 4.0 and they need to be opened in a version 3.0 system. Is there any way to save the files created in a 4.0 system as a 3.0 file?

Hello,

you cannot save as an older version but you can open a newer version with WF3.

You just have to use GCRI:

GRANITE-Based Cross-Release Interoperability (GCRI) for Pro/ENGINEER
GCRI is a plug-in application enabling interoperability between Pro/ENGINEER releases. It allows a Pro/ENGINEER Wildfire 2.0 or later release user to open, modify and save parts and assemblies created in a more recent release of Pro/ENGINEER. Later release users can bring forward features added to GCRI models in earlier releases and recover the full feature and model definition.
