Recommendations

Autodesk strongly recommends that users of the 2021 and 2022 versions of the affected products listed in the table above install the latest 2024 updates, as applicable, via Autodesk Access or the Accounts Portal. As a general best practice, we also recommend that customers only open Parasolid files (*.x_b) from trusted sources.

Customers using previous versions that no longer qualify for full support should plan to upgrade to a supported version as soon as possible to avoid downtime and potential security vulnerabilities. Visit the Autodesk Knowledge Network for more information about previous version support.
