Naviswork: Manage
Navisworks Manage: Ultimate Guide to Model Coordination and Clash Detection
Navisworks Manage is Autodesk’s advanced project review and coordination tool for AEC teams, designed to aggregate 3D models and 2D data from multiple disciplines into a single environment for visualization, clash detection, and construction simulation. This post explains what Navisworks Manage does, when to use it, key features, best practices, and a simple workflow to get started.
Verdict: Is it worth the cost?
| Use Case | Do you need Navisworks Manage? | | :--- | :--- | | I just need to look at models and measure distances. | No. Use Navisworks Freedom (Free). | | I need to print views and markup PDFs. | No. Use Bluebeam or Adobe. | | I have 15 trades (Struct, Arch, MEP, Fire, AV). | Yes. Without Manage, you will have collisions. | | I am a GC responsible for schedule and coordination. | Yes. The TimeLiner and Clash Detective are worth the subscription. | | I am an MEP contractor who self-performs clashes. | Yes. But consider Navisworks Simulate (cheaper, no clash detection). |
How Navisworks Manage Fits into the BIM Workflow
| Stage | Role of Navisworks Manage | |-------|--------------------------| | Design Development | Regular model aggregation to ensure structural and MEP systems fit within architectural spaces. | | Preconstruction | Running clash detection reports; assigning clashes to engineers; 4D simulations for bid packages. | | Construction | Weekly coordination meetings with model as the centerpiece; tracking RFIs (Requests for Information) linked to clashes; 5D takeoffs for change orders. | | Handover & Facilities | Exporting as-built models (with metadata) for owner's asset management systems. |
4. Redlining and Review
Real-time collaboration is supported via the Review and Redline tools. Project managers can host a live coordination meeting inside the NWD file, pan around the model, add viewpoint bookmarks, and draw red arrows or notes directly on the screen. These sessions can be saved and exported as HTML reports for team members who lack the software.
System Considerations & Best Practices
- Performance: Large models (e.g., 500+ MB .nwd files) require a capable workstation. Use selection trees and hiding/disabling irrelevant geometry to improve navigation.
- File Naming & Standards: Adopt a clear naming convention for clash tests (e.g., "Week12_Mech_vs_Struct_Clearance_100mm") to avoid confusion.
- Coordination Schedule: Run clash detection weekly, not daily, to allow time for resolution. Assign a single clash manager to prioritize issues.
- Publish NWD, not NWF:
.nwf(Navisworks File) – references original source files; updates automatically when source changes. Best for internal coordination..nwd(Navisworks Document) – a single, published, lightweight file with all geometry and viewpoints. Best for sharing with clients or field teams.
Navisworks Manage vs. Navisworks Simulate vs. Navisworks Freedom
To understand the value of Manage, you must distinguish it from its siblings: naviswork manage
- Navisworks Freedom: A free viewer. You can open and view NWD files, but you cannot save, measure, or run clash tests.
- Navisworks Simulate: Adds advanced 4D scheduling (timelines) and photorealistic rendering. Great for presentations, but lacks clash detection.
- Navisworks Manage: Includes everything from Simulate plus the advanced clash detection and interference checking tools. Manage is the workhorse for coordination managers.
Conclusion
Autodesk Navisworks Manage is more than just a viewer; it is the central nervous system of the BIM process. By aggregating data and facilitating clash detection and 4D simulation, it shifts the construction paradigm from "detect and repair" to "predict and prevent." For any organization serious about Digital Twin technology and lean construction practices, Navisworks Manage is an indispensable asset.
Developing a "helpful story" in Navisworks Manage usually refers to creating a compelling project narrative through coordination, visualization, and 4D simulation. By effectively using the software's tools, you can transform complex data into a clear story that stakeholders can easily understand. 1. Identify the "Clashes": The Conflict
The first step in any project story is identifying the problems. Navisworks Manage is unique because it includes Clash Detective, which allows you to find "conflicts" between different design disciplines (e.g., a pipe running through a steel beam).
Proactive Review: Use the Clash Detective to find issues early in the design stage, which is much easier and cheaper than fixing them during construction. Navisworks Manage: Ultimate Guide to Model Coordination and
Isolate Issues: Focus on "floaters" (floating objects) and "disconnects" (unconnected lines) to clean up the model before meetings. 2. Visualize the Journey: The Walkthrough
A great story needs a setting. Use Saved Viewpoints and the Animator tool to guide your audience through the building as if they were walking it in person.
Save Key Views: Create "Saved Viewpoints" for critical areas of the project. You can add redlines, circles, and comments to these views to communicate specific issues to your team.
Create Animations: Stitch these viewpoints together to create a smooth flythrough or walkthrough. This helps non-technical stakeholders "see" the finished project before a single brick is laid. 3. Build the Timeline: The Plot System Considerations & Best Practices
The "plot" of your project story is the construction schedule. The TimeLiner tool allows you to link your 3D model to external scheduling data (like Microsoft Project or Primavera). Autodesk Navisworks Walkthrough
Navisworks Manage: The Ultimate Guide to BIM Coordination and Project Review
Navisworks Manage is a comprehensive project review software by Autodesk that enables architecture, engineering, and construction (AEC) professionals to holistically review integrated models and data. Unlike authoring tools like Revit, Navisworks is designed for coordination, allowing users to combine diverse 3D design files into a single, unified project model for better control over project outcomes. Core Capabilities of Navisworks Manage
Navisworks Manage stands out for its ability to handle large, complex datasets from multiple disciplines, providing a "single source of truth" for project stakeholders.
TimeLiner for Site Logistics
Don't just use TimeLiner for building installed objects. Use it for temporary works: cranes, safety netting, concrete pumps, and material stockpiles. Showing the crane moving out of the way on Week 5 is worth a thousand words to a superintendent.
