Work with Autodesk Vault from within Autodesk Civil 3D, or use a separate administration tool.
Within Autodesk Civil 3D, you can use the Toolspace Prospector tab to interact with Autodesk Vault. Another method is to use the Autodesk Vault Client. In some situations, there are distinct advantages to using one of these methods over the other. You can also check Vault files in and out from some Microsoft Office applications.
