Unwanted Regen

[MP_7750864]

1. MCAD Architect, ME Team depends on my CAD for their models.
2. Creo 7, recently switched from Creo 4
3. We are experiencing unwanted file regeneration.  Files are regenerating without change and are saved.  This seems be happening whenever a part file with a copy geom references another file's publish geom that has more than one quilt.

Have you tried contacting tech support? Link: https://support.ptc.com/apps/cs_loggers/case_logger/auth/ssl/log

I have tried that.  No luck yet.

You need to supply more information to have someone here attempt to identify what the problem may be. Have you used the global reference viewer in Creo 4 and Creo 7 on the same set of models? If so, are there any differences indicated with the dependencies?

Can you post an example set of models in Creo 4 format that we can test?

Thank you for your attention.  I have used the reference viewer without success.  The issue is happening in Creo 7 and not in Creo 4.  Files created in Creo 4 don't seem to have the issue when opened and/or saved in Creo 7. Below are steps to reproduce the issue:

1. Build a file with two quilts
2. Build a publish geom with those two quilts.
3. Build another file with a copy geom referencing that publish.
4. Save the files.
5. Close the files and erase from session.
6. Open the file with the copy geom of the publish.
7. Save the file again.
8. The file should not regen and save because no changes were made.

I just followed your test protocol in Creo 7.09.  There is no regeneration of the model when retrieved (step 6). The model will save but that is not any different than any other model in Creo 7.

I gather that you are expecting a model that has not been modified to not be saved. If I missed something about where a regeneration is occurring with your models, please elaborate.

Are you expecting to get a command line message indicating that the part has not changed since last regen and is not saved? Is Windchill in use in this context?

Thank you tbraxton, that is a potential solution. We are using Creo 7.0.2.0.  I'll look into another build of Creo 7.0.

Internally the file structure of a part saved in Creo 4 and then opened in Creo 7 will change.  There may be something in the way Creo handles the copy geoms and quilts that Creo thinks there is enough change that it needs regenerated and saved. Normal files do not and they remain at Creo 4 file formatting until the user does an explicit save.
