Autodesk Navisworks Simulate: Complete Guide for Project Coordination
What it is
Autodesk Navisworks Simulate is a project review and 4D simulation tool for construction and design teams. It aggregates models and data from multiple formats into a single, navigable environment to support coordination, visualization, and presentation without requiring native design software.
Key capabilities
- Model aggregation: Combine files from Revit, AutoCAD, IFC, SketchUp, and many others into one consolidated model.
- 4D simulation (time-based): Link construction schedules (e.g., from Primavera or MS Project) to model elements to visualize sequence and duration.
- Clash avoidance support: While clash detection is more advanced in Navisworks Manage, Simulate supports model review workflows that help identify coordination issues early.
- Quantification: Basic takeoffs and material measurements to estimate quantities.
- Visualization & presentation: Walkthroughs, viewpoints, animations, and sectioning for stakeholder reviews and client presentations.
- Markup & redlining: Annotate models with notes, flags, and comments for team communication.
- File format support: Wide compatibility with BIM and CAD formats via native readers and the Autodesk NWC/NWD formats.
When to use Simulate vs Manage
- Use Simulate when you need model aggregation, 4D sequencing, visualization, and presentation features without advanced clash detection or extensive project coordination workflows.
- Use Manage if you require automated clash detection, clash tracking, rule-based clash tests, and richer coordination issue management.
Typical project coordination workflow
- Collect models: Gather federated discipline models (architectural, structural, MEP) in their exported formats.
- Append models: Import and align models in Navisworks Simulate, checking units and origins.
- Clean & organize: Hide irrelevant geometry, set search sets, and create folders/viewpoints for review.
- Link schedule: Import an MS Project or Primavera schedule and map tasks to model elements for 4D simulation.
- Run simulations: Play sequences to visualize construction progress and detect sequencing conflicts.
- Annotate & share: Add markups, export NWD/NWF packages, and distribute for stakeholder review.
- Iterate: Update models and schedules, re-append and re-run simulations as designs evolve.
Best practices
- Standardize coordinates and units before appending to avoid misalignment.
- Use Search Sets to quickly isolate disciplines or systems (e.g., all HVAC ducts).
- Keep models lightweight: Hide or purge unnecessary detail to improve performance.
- Name viewpoints consistently for clear communication with stakeholders.
- Version control: Use dated NWD/NWF snapshots to track changes across iterations.
- Validate schedules before linking to ensure task-element mappings are correct.
Limitations to be aware of
- No automated clash detection workflows like Navisworks Manage.
- Performance can degrade with very large federated models; hardware limits apply.
- Quantification is less advanced than specialized estimating tools.
Learning resources (recommended)
- Autodesk Knowledge Network articles and official Navisworks tutorials.
- Autodesk University classes and recorded sessions.
- Community forums, YouTube walkthroughs, and CAD/BIM blogs for practical tips.
