I'm using Navisworks Manage 2013 and opened a rvt model. See attached screenshot. Area boundary lines and detail lines are visible in Navisworks that are not visible in Revit. Since I can't even see or select these in Revit I'm not even sure what these lines are. I know I can hide them in NavisWorks, but I'm guessing this will occur again so I would like to no how to resolve in Revit so they won't show in Navisworks.
I would select the elements in Navisworks grab the Element ID's in the Properties. Then you can then take those element ID's into Revit, got to Inquiry > Select by ID, and select the elements. You can then hide them in Revit, then go to a 3D view and export the view to Navisworks (instead of opening the .rvt file in Navisworks).
