|---|
| Multiple Revit application processes seen when user opening multiple files. User can have the cad application running before doing a multi-select file open from vault client. PDM-49163 |
| TXT files opens with 15 sec delay when using opening multiple files from Vault. PDM-49086 |

| Add-ins: Inventor |
|---|
| When using the Open drawing from Vault command from the context menu in the Inventor Vault Add-in for a modified and checkedout file, a "Confirm File Replace" dialog appears. If the user clicks "Yes," the local modified file is replaced by the released version from Vault, leading to the loss of all unsaved modifications upon the subsequent Check-in operation. To prevent data loss, do not click "Yes" in the "Confirm File Replace" dialog. PDM-49265 |
| Add-ins: Inventor: Content Center |
|---|
| When attempting to Copy a Custom Content Center library on the Vault Server, the error: "This library cannot be copied; it's partition cannot be updated to any other partition" appears. This issue is observed when the library's partition is an older Inventor version than the target partition, or when attempting to copy the library to the same partition version. As a workaround use the Inventor Library Transfer Guide to transfer the library from the Vault Server to a local desktop, create a new library, and then transfer the new library back to the Vault Server. PDM-49323 |
| Vault Connector |
|---|
| Attaching very large size files (size > 1 GB) from Vault to Fusion manager items fails. PDM-47750 |
| Incorrect error message is seen when user tries to sync Item, without setting up the Vault Connector mapping. PDM-47670 |

| Enabling a Vault Connector setting is not possible if the user account lacks direct access to all Vaults. Indirect access—such as through group membership—is not recognized. |
