You have configured the Vault revision table in AutoCAD and you noticed that it doesn´t update after updating the properties in AutoCAD.
Check the Connectivity.VaultPro.exe.config (open it via notepad) from C:\Program Files\Autodesk\Vault Professional 2014\Explorer
Navigate to the key UpdateRevBlockOnSyncProp and make sure that it is set to 1:
0 Turns OFF Update Revision Table during Synchronize Properties
1 Turns ON Update Revision Table during Synchronize Properties
Default is 0
<add key="UpdateRevBlockOnSyncProp" value="1"/>
After changing the value of UpdateRevBlockOnSyncProp to 1 and restarting AutoCAD the revision table should be updated either on the automatic property update (if answer is yes):
...or the Update Property button in the Vault ribbon:
Please not that you would need to restart Jobserver as well if Jobserver is used.
