NWC Export from Revit is fast and accurate. It generates small files with nice geometry with textures. This is brilliant for use in NavisWorks.
However.. to utilize BIM you have to have control over the information in the Model. When exporting to IFC you get triangulated geometry, no textures, BUT control over the information. The user can specify User Defined Property Sets, wich is an important feature.
I would really like to combine the best from nwc and IFC export -> NWC Export with User Defined Property Sets.
