When opening a drawing created in AutoCAD MEP 2012 in NavisWorks Manage 2013, it only renders the 2013 pipes, but the rest of the frames do not render. This only happens when the drawing is opened on an identical computer, with only MEP 2013 enabled and the same object enabler packages.
Does the drawing need CAD MEP 2012 installed as well to render all of the pipes in NavisWorks Manage correctly?
