Import Naviswoks File

I am using CADWorx 2017 and have an existing Navisworks file I would like to Import.
How is this best done

Thanks
Craig

Depends on what you want to do. You can attach the .nwd file as an XREF (Coordination Model) and view it in AutoCAD, but you can only snap to centers or endpoints.
Alternately, you can export the model from Navisworks to a FBX file and import this into AutoCAD, but you will loose any intelligence (layers, colors, line numbers, pipe size, etc)
