The Revit Plug-in for Vault Professional (Server) allows Vault to deeply index Revit family files, including parameters and objects, so that you can search Revit family files with the Revit Vault Add-in.
The Revit Interoperability add-in is installed during the Vault Server installation. You must customize the Vault Server options to include Revit interoperability on the Configure Installation screen.
Once you install Revit Interoperability, the Revit Indexing feature must be enabled in the Autodesk Data Management Server Console before you can use Revit Family Search.
Enable Revit Indexing with the ADMS Console
You can also select Revit Indexing Service from the Actions menu.
You can now use Revit Family Search on the Load from Vault dialog.
