I am trying to Export an Infoworks WS model to AutoCAD 3D Civil. I have found that due to the fact that InfoWorks models valves and other fittings as a link rather than a node. When the model is exported the valves are duplicated at each node with pipework replacing the link the valve was situated on.
this creates a laborious task of manually deleting valves throughout the model.Is there a way of ensuring that only one valve comes through in the export?

Thanks for any help!
