It is important that users working in collaboration with customers, suppliers, and other users ensure that all models are saved in the same version and release of CATIA.
CATIA is only backwards compatible, meaning that if the user saves a file in CATIA V5R20, they would no longer be able to open the models in an earlier release such as CATIA V5R18. The naming format changes with later releases of CATIA V5 which are compatible with ENOVIA V6. These release numbers are defined in a format whereby the year of release is identified; e.g. CATIA V5-6R2015. In this example, the version of CATIA is still V5 and the release can be ‘nicknamed’ R25.
