The contractor is using Architects Revit model to do clash detection in Naviswork.
And the ceilings are not showing up in Naviswork. It randomly started, because it was working before. Nothing really changed in the Architects Revit model. I manually upload Architect revit model onto ACC, and contractor downloads it then links it to Naviswork.
They don't see any sort of ceilings. We double checked the worksets, phasing, etc. Not sure why it isnt showing up in Naviswork. It shows up in Revit.
