Work with Files
You can combine these files together, and create a single Autodesk Navisworks file
with a whole-project view of your model. This file brings together geometry and
data created by multi-disciplinary teams, and enables you to explore and review
complex models in real-time.
Native File Formats
Autodesk Navisworks has three native file formats: NWD, NWF, and NWC.
NWD File Format
An NWD file contains all model geometry together with Autodesk
Navisworks-specific data, such as 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.
NWF File Format
An NWF file contains links to the original native files (as listed on the Selection
Tree) together with Autodesk Navisworks-specific data, such as review markups.
No model geometry is saved with this file format; this makes an NWF
considerably smaller in size than an NWD.
NWC File Format (Cache Files)
By default, when you open or append any native CAD or laser scan files in
Autodesk Navisworks, a cache file is created in the same directory and with the
same name as the original file, but with an .nwc file extension.
