For those of you who have been looking for a way to open Intergraph VUE files directly in Navisworks, there is an Autodesk Labs project that may interest you. Viewing Intergraph Smart™ / SmartPlant 3D® VUE files in Autodesk Navisworks is alive in the Labs!
When you consider the ability for Autodesk Navisworks to now display coordination models (NWD and NWC) in AutoCAD Plant 3D 2016 and include Navisworks' ability to aggregate models from many sources (including point clouds), we are seeing collaborative plant design rising to a new level.
