The Revit Server is installed in worksharing environments to enable project design collaboration for Revit project teams across wide area networks (WANs).
In a Revit Server worksharing environment, it is recommended that the system administrator first install and configure one central server on a WAN, and then install and configure the local servers on their local area networks (LANs).
There is normally one local server at each office site that accesses the Revit project content from the central server.
