Creo 11 saves unchanged Components when saving only one assembly

[richardschmitz]

We switched to Creo Parametric 11.0.5.0 on Monday.

Now we’ve noticed that when we save an assembly that hasn’t been modified, all the contained parts and assemblies that are in an older Creo version are also being saved. In one example, 160 out of 211 Creo files were saved. The config.pro save option is set to save_objects changed_and_specified. Even save_objects changed has no effect.

The problem is that our document management tool “Workspaces Desktop” from the company Contact interprets this as a change and now considers all these documents as modified, wanting to save them or even re-index documents that have already been released. That would be disastrous.

Has there been an adjustment on PTC’s side? This behavior was definitely different in Creo 9 and previous versions! It’s not related to versioning. That option should remain active.

This is about saving files that have not been changed. We just tested again with Creo 9 using a different assembly. Same procedure: once with Creo 9, once with Creo 11—different result. Many more files are being changed. There were even Creo files from version 7 included. These were not changed by Creo 9, but they were changed by Creo 11.

Hi,

Creo 10.0.5.0, Creo 11.0.1.0 and Creo 12.0.0.0 will stop modifying old files using the hidden config.pro:

prevent_silent_sync yes/no*

hidden means that you have to add prevent_silent_sync YES to config.pro manually in Notepad and restart Creo.

Hello Martin.

Thank you very much for your suggestion! Setting the config.pro option prevent_silent_sync to YES has achieved the desired result!
