Manage: Navisworks
If a steel beam doesn't have a property called "Level," you cannot easily sort by level. Before clashing, ensure model authors export Properties correctly from Revit (Project Parameters must be shared).
The true power of Navisworks Manage lies in its legendary file format support. It acts as a Rosetta Stone, translating over 60 different native CAD and BIM formats into a single, usable environment. Key formats include:
The distinction between NWF and NWD is critical. An NWF file is a lightweight "pointer" file. It stores links to the original source files, clash test results, and viewpoints, but contains no actual geometry. This allows teams to update source models, refresh the NWF, and instantly see changes. An NWD file, conversely, is a "published" or "snapshot" file that contains all the geometry. It is used for distribution, as it cannot be edited, making it a secure deliverable for clients and site teams. Navisworks Manage
Construction is a sequence, not a snapshot. Navisworks Manage allows you to attach time data (4D) and cost data (5D) to your model via the Timeliner tool.
Large models are overwhelming. The Sectioning tool allows you to slice the building horizontally or vertically. You can create "plane sets" to save specific cut views (e.g., "Level 2 MEP Riser View"). If a steel beam doesn't have a property
This is a lifesaver. If you find a missing pipe in Navisworks, you can right-click the object and select SwitchBack. If that object came from Revit, it automatically opens Revit, loads the project, and selects that exact pipe. You do not have to search for IDs manually.
If you are trying to group several objects together to save them for later viewing, you are looking for Selection Sets. The distinction between NWF and NWD is critical

Navisworks Manage is more than a piece of software; it is a methodology. It embodies the principle of "build it twice—first digitally, then physically." By providing a unified, data-rich environment where different disciplines can see their work in context, it transforms construction from a series of conflicting trades into a symphony of coordinated effort. For any project where complexity is high and the margin for error is zero, Navisworks Manage is not just a valuable tool—it is an indispensable strategic asset. It saves money, saves time, and ultimately, builds better buildings.
