"Free NavisExport" is a free Autodesk® Revit® Add-in that makes batch export of Revit models and 3D Views to Autodesk® Navisworks® "NWC" files possible.
A simple user form allows the user to select the models to be exported (whether they are in the same directory or in separate directories) and the output folder.
The entire models can be exported automatically, which is a huge time saver. The user can also specify individual 3D views to be exported across several models based on a view name keyword, and all Navisworks Export settings can be specified through the user interface.
This add-in requires Autodesk® Navisworks® Manage or the Navisworks® NWC Export Utility to be installed.
