Navisworks

Navisworks is project review software from Autodesk (originally from a separate company which was later acquired by them) to improve BIM (Building Information Modeling) coordination. It generates 3D models with both design and construction data. It is offered on a subscription model. It supports a number of file formats in addition to its own native NWD/NWF/NWC formats.

File formats

 * NWF files contain an index to model files and other Navisworks data. It requires the original CAD files to accompany it.


 * NWD files store all the information of an NWF file, as well as the geometry of the model; it makes a self-contained file which doesn't require other files. Only licensed users can create these.


 * NWC files are created by import/output features, and use cached geometries in a form that can be loaded quickly. It is not a format you can save to.

Software
