someone knows if it is possible to save files from creo to previous versions of pro|e ..type wf5 or wf4 . I had seemed to understand that you could do , but I did not find this functionality either with creo 1.0 or with creo 2.0.
Clearly if you already create there is no need to download and install anything because it is already all included in the installation files.
You just have to try and tell us what's going on
rescue in granite can be done with creo 2.0 with "save copy" / catia v5 cgr . the file generated after saving .cgr you can import from wf4.0 onwards.
the new imported file has model tree, but it is not editable or at least does not maintain the information and constraints of native creo 2.0 assembly.
the advantages regarding the passage from .step or .iges is practically irrelevant .
