Navisworks utilizes a proprietary file format, the (Navisworks Document), or a lightweight, indexable .nwc cache. When a user opens a model in Navisworks, they are looking at a snapshot of geometry.

In Revit or SolidWorks, you work in a silo. In Navisworks, you aggregate everything. You bring the architectural model, the MEP (mechanical, electrical, plumbing), and the structural steel together in one federated model.

While not a replacement for dedicated takeoff software, the Quantification tool lets you perform interactive material takeoffs directly from the federated model. You can instantly generate the surface area of drywall or the linear footage of piping.

This is the defining feature of the "Manage" license. The Clash Detective compares geometry against geometry to identify interferences—known as "clashes."

Navisworks Manage sits at the summit of the BIM workflow. Its primary value lies in its ability to aggregate 3D models from over 60 different file formats (including Revit, AutoCAD, SketchUp, Rhino, and IFC) into a single, cohesive environment.

With the rise of Autodesk BIM 360 Glue (now part of ACC) and Revit's native collaboration tools, some argue that Navisworks is legacy software.
