The video below demonstrates how the 
            ImportCivilStyles and 
            ExportCivilStyles 
            commands may be used to transfer Civil 3D Styles between a variety of sources, 
            quickly and easily.  And yes, this demonstration is at actual speed, and 
            the Sincpac-C3D really does transfer hundreds of styles in only a second 
            or two!
        
            The tasks illustrated in this demonstration require the Drafting Module of the Sincpac C3D,
                and may be performed in Civil 3D 2010 SP2 and later.
