We are currently engaged on a very large metro project here in Doha, Qatar. We have in excess of 600 models for one line alone. During modelling in Revit 2015, we represent proposed tiled wall and ceiling finishes as surface/model patterns. These are not exported to Navisworks NWC or DWFX making the technical, visual and coordination review of finishes in the models impossible using Navisworks 2017 without Revit or drawings. Please consider re-enabling this feature we had before the change in Revit 2014 its a must have feature.
As I can't find anywhere to add this suggestion for Navisworks I've placed in in the Revit section in the hopes it will at least be seen so apologies to the admins in advance.
