Recommendations

Autodesk highly recommends that customers using the affected products listed above apply the available hotfix for their version via the Autodesk Desktop App or the Accounts Portal, as soon as possible.

Customers using Storm and Sanitary Analysis with AutoCAD Map3D will need to update the Storm and Sanitary Analysis Add-on through the Accounts Portal under AutoCAD Map 3D Updates and Add-Ons.

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.
