NWD File Converter
We can't convert Navisworks Document (NWD) files — here's what does work.
Why NWD can't be converted here
NWD is Navisworks's own closed format. Its internal structure is proprietary, so no open-source library can read it — which is why no converter outside Navisworks can open your file.
What does work: open the file in Navisworks and export it as IFC. We convert IFC reliably.

Navisworks Document (NWD) is a 3D file format used primarily for Construction and BIM.
NWD is Autodesk Navisworks' aggregated, display-only format that combines multiple federated CAD/BIM models into one file for clash detection and 4D construction review — it keeps the visual geometry but drops each source model's parametric edit history.
