After spending some time on the Autodesk Labs, the Autodesk Vault 2013 Integration for MicroStation is now available for download from the Autodesk Subscription Center under Downloads>Product Enhancements.
The MicroStation integration for Vault enables MicroStation V8i users to connect to Autodesk® Vault Collaboration AEC 2013 from within MicroStation, permitting MicroStation users the ability to manage their design data from within their design tool. Specifically, the integration provides users the ability to manage file versions via check in and check out, manage file references, manage title block attributes, batch plot, get Vault status, and dynamically create visualization files for sharing data with downstream non-CAD users. This integration also works with Vault Workgroup, Vault Collaboration, and Vault Professional.
There are components of this integration that reside on both the client and server machines, as well as the DWF publisher which resides on the Job Processing machine. Please refer to the administrative guide for more details on installation and use.
