I have made an extensive library of parts already in inventor and am trying to get them into Revit Systems families with intelligent geometry. Right now I save the parts as dwg files and then import them into the family, but I can't select any faces to paint, apply connectors, etc. I have to create an extrusion over the part where I want the connector. I tried to use the explode feature, but I got a message saying that the model contained 3D data points. Anyone have any suggestions?
