Revit has a new tool in 2012 that divides a single element into parts, but still maintains an optional single identity of the object. I've broken a wall into panels, exported the model to navisworks using the external tool for Navisworks Manage 2012, and upon opening the file in navisworks, the walls are not visible.
Are there settings I need to adjust? I have not seen anything unchecked in my vg settings in revit. Any help would be appreciated.
