Autodesk Navisworks comes with MDL plugins for MicroStation™ J, v8, and v8.9, and enables you to export files into NWC file format.
Note: If you installed the Autodesk Navisworks software with exporter plugins, and you install MicroStation software after Autodesk Navisworks is installed, you need to update your exporter plugins installation with the appropriate ARX plugins before you can use them.
