Navisworks Flashcards

What is the primary purpose of Autodesk Navisworks?

Answer: 3D model review, coordination, and clash detection

Navisworks is designed for project review, coordination, clash detection, and 4D simulation across multidisciplinary BIM models.

Which file format is native to Navisworks and contains the full model with all data embedded as a published, self-contained file?

Answer: .nwd

The .nwd (Navisworks Document) format embeds all model geometry and data in a single published file that can be shared without source files.

What does the .nwf file format in Navisworks represent?

Answer: A file that stores links to source files and saved viewpoints without embedding geometry

The .nwf (Navisworks File) stores references to source files along with saved viewpoints, clash results, and comments, but does not embed geometry.

What is the function of the Selection Tree panel in Navisworks?

Answer: Displays a hierarchical view of all objects in the loaded model

The Selection Tree provides a hierarchical tree structure showing all loaded files and their model elements, allowing users to select and manage objects.

In Navisworks, what does a Viewpoint save?

Answer: A specific camera position, orientation, and visual state of the model

A Viewpoint saves the current camera position, orientation, section planes, hidden/required objects, and visual overrides so you can return to that exact view later.

Which navigation mode in Navisworks simulates walking through a 3D model at a set eye height?

Answer: Walk

Walk mode simulates a first-person perspective at a specified eye height, allowing users to navigate through the model as if walking through a building.

What is a Navisworks Cache file (.nwc)?

Answer: A temporary file automatically created when a native CAD file is opened, storing converted geometry for faster loading

An .nwc file is automatically generated when Navisworks opens a native file such as Revit or AutoCAD, caching converted geometry for faster subsequent loading.
