NWD Files
An NWD file is a file created with Autodesk Navisworks publisher tool, and
contains all model geometry together with review markups. You can think of
an NWD file as a snapshot of the current state of the model.
NWD files are very small, as they compress the CAD data by up to 80% of the
original size.
DWF/DWFx Files
Autodesk DWF was specifically developed by Autodesk as a file format for
architects, engineers, and GIS professionals to share 2D- and 3D- design data.
DWF files are highly compressed and retain detailed design information and
scale. The newest version of the DWF file format, DWFx, is based on the XML
Paper Specification (XPS) from Microsoft. DWFx files can be opened and printed
instantly using the free Microsoft XPS Viewer, which comes pre-installed on
computers using the Microsoft Windows Vista
®
operating system. (For the
Windows XP operating system, the Microsoft XPS Viewer can be downloaded
directly from Microsoft.) Unlike DWF files, DWFx files include additional
information to display design data in the Microsoft XPS Viewer. As such, DWFx
files are larger than corresponding DWF files.
