What format does a Navisworks Document use for exporting?

The correct choice is NWD because it represents the file format specifically designed for exporting data from Navisworks. NWD files contain the compiled, viewable data that includes the model geometry, the associated properties, and the viewpoints created within Navisworks, making it an ideal format for sharing the visual representation of the project with stakeholders who may not have access to the original software.

NWF, while related, is primarily a project file that references separate models and views used within Navisworks rather than being an exported format. DXF is a widely used format for two-dimensional and three-dimensional drawings but is not unique to Navisworks and does not encapsulate all the special features produced by Navisworks. IFC (Industry Foundation Classes) is an open data model standard for BIM that facilitates interoperability between different software platforms, but it is not specific to Navisworks and is used primarily for exchanging information rather than viewing. Thus, NWD is the appropriate format for exporting Navisworks presentations and models.
