Revit objects loosing level parameter

[whilgendorf]

When exporting a Revit model into Navisworks I have some families that loose their level. When I select on them in Navisworks they don't have a level associated with them. I found that in some of the families I can change them from being faced based and then they pick up the level property. Mostly it is plumbing and things like that. ANy help would be appreciated.

Many of the Revit MEP families are going to be face-based elements and need to be that way. So if there is an issue with Navisworks not picking that up, it needs to be reported to Autodesk.
