- ✓No Navisworks license needed, View NWC discipline model files without any Navisworks software
- ✓Works on any device, Navisworks is Windows-only, ShareCAD works in any browser on any OS
- ✓Secure sharing, Share model geometry via expiring links with optional password protection
- ✓Individual discipline review, Review architectural, structural, or MEP models independently before federation
- ✓No account for recipients, Project partners open shared files without creating an Autodesk account
What Is an NWC File?
NWC (Navisworks Cache) is the export format used when individual design applications, Revit, AutoCAD, Civil 3D, and others, publish geometry into the Navisworks coordination workflow. NWC files contain the geometry and object properties from a single discipline model, ready to be aggregated with other NWC files into a federated NWD coordination model.
While NWC files are primarily an intermediate step in the Navisworks workflow, there are many situations where viewing an individual discipline model, before federation, is useful. An NWC viewer online through ShareCAD makes this possible in any browser, without Navisworks installed.
Architects, structural engineers, and MEP consultants can share their NWC exports directly with project stakeholders or coordination leads for early review, without waiting for the full NWD to be assembled.
NWC Viewer Use Cases
Pre-federation discipline review
Review individual NWC exports from Revit, AutoCAD, or Civil 3D before combining them into a federated coordination model.
Coordination lead check-in
BIM coordinators can view NWC files submitted by subcontractors to verify geometry quality before federation.
Subcontractor model sharing
Subcontractors share their NWC model exports with the coordination lead or client via a browser link for progress tracking.
Early clash spotting
Review individual discipline NWC files to identify obvious issues before formal clash detection runs in the full federated model.
