Navisworks | Autodesk

In the modern world of Architecture, Engineering, and Construction (AEC), the difference between a successful project and a catastrophic failure often comes down to one thing: coordination. With the rise of Building Information Modeling (BIM), project teams generate massive amounts of 3D data. But creating models is only half the battle. The real challenge lies in aggregating, reviewing, and analyzing those models to catch clashes before concrete is poured.

Enter Autodesk Navisworks—the industry-standard solution for project review and coordination. If you have heard the term "BIM coordination" but aren't sure how it works in practice, this guide will walk you through everything you need to know about Autodesk Navisworks, from its core functionality to advanced workflows.

Navisworks doesn't care if your model is bad; it just shows you what you have. If you run clash detection on a model with "LOD 200" (generic placeholders), you will get thousands of false-positive clashes. Ensure your models meet LOD 350 (coordinated with clear geometry) before running hard clash tests.

The primary reason firms invest in Navisworks Manage is to run clash tests. A "clash" is where two different components of a building illegally occupy the same space. Freedom = free viewer only (no editing, no clash)

For example:

Navisworks automates the search for these conflicts. Within minutes, the software can scan a complex building with millions of components and produce a report listing every single clash. It categorizes them by severity (hard clash vs. clearance clash) and allows project managers to assign these clashes to specific team members to resolve.

To understand the value of Navisworks, you need to look at its five core pillars.
