I am troubleshooting an issue whereby some Revit MEP element parameters report inproperly in the Navisworks Properties palette. For instance, the "Flow" parameter of a Duct instance in the Revit file (150 CFM) is reporting (2.50 ft3) in NVM 2013. This is happening across all readable formats which include reading the native RVT and DWFx/NWC exports. I have the File Reader for Revit set to Convert element parameters for Elements but, not to Convert element properties hoping that this would retain the original Revit data.
When I open the DWFx in Design Review 2013, the Flow reports properly. Is this a bug in NW?
