Thanks for your help. The links to videos and the Norwegian lecture is useful. I don’t think the Vectorworks route would suit us as our internal architectural team use Revit exclusively. It looks like we might have to get training on both Revit and Civil3D and use whichever is appropriat to the situation. I intend to talk to some engineers to find out how well Civil3D works as BIM and also to see how well it communicates with Revit
