.nwd

Extension: Navisworks Document

Developer: Autodesk

The .nwd file extension, short for Navisworks Document, is a proprietary format created by Autodesk. These files are crucial for collaborative project review in the architecture, engineering, and construction (AEC) industries. A single .nwd file can contain a comprehensive 3D model, encompassing not only the geometric data representing the building or infrastructure, but also crucial metadata like materials, lighting specifications, and even linked design documents. This allows for a holistic view of a project, facilitating better coordination and clash detection among different disciplines involved. Annotations and hyperlinks can be embedded directly within the model, making it easier to track changes, highlight issues, and share specific information with stakeholders. The size of .nwd files can vary significantly depending on the complexity of the included model and data.

Opening .nwd files requires Autodesk Navisworks software. While other Autodesk products might offer limited functionality with .nwd files, full access to the model’s features and data necessitates a licensed copy of Navisworks Manage or Navisworks Simulate. These programs allow users to navigate, analyze, and manipulate the 3D model, providing tools for clash detection, quantity take-offs, and simulation capabilities. It’s important to note that simply having the .nwd file doesn’t guarantee access to all its contents; proper access permissions and potentially associated data files might be necessary for complete viewing and utilization. If you lack Navisworks, requesting the project data in a more widely compatible format from the project owner might be necessary.
