What survives the conversion
A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from Navisworks into USDZ, and what does not.
| Geometry | Kept | Both formats store triangle meshes, so the shape transfers directly. |
|---|---|---|
| Colors and materials | Kept | USDZ carries full PBR materials, which is at least what Navisworks stores, so the colors come across. |
| Units and scale | Kept | USDZ stores an explicit unit, so the model opens at true size without rescaling. |
| Lines and points | Dropped | AR Quick Look renders neither lines nor point clouds, so only the triangle meshes are written. |
What the USDZ writer emits: An uncompressed, 64-byte-aligned USDZ holding a USD layer with UsdPreviewSurface materials and any baseColor texture. Lines and points are skipped because Quick Look renders neither.
The source: Autodesk Navisworks (NWD / NWC) (.nwd, .nwc)
Every placed part of a Navisworks model or cache, drawn from the tessellated shapes Navisworks stores, at the position and in the material colour it saved, with grid and centre lines as lines. A shape used many times is decoded once and placed at every use. Models exported from Revit are in feet; the rest keep the file’s own units. A project file (.nwf) opens to a notice naming the models it links.
The target: USD for AR Quick Look (.usdz)
Apple AR: tap the file on an iPhone or iPad and the model stands in the room.
Opens in: iOS and iPadOS AR Quick Look, visionOS, macOS Preview, Reality Composer.
Your file never leaves your computer
Both the Navisworks parser and the USDZ writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.

Frequently asked questions
▶Is this Navisworks to USDZ converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my Navisworks file uploaded anywhere?
No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.
▶Will my colors and materials survive the USDZ export?
USDZ carries full PBR materials, which is at least what Navisworks stores, so the colors come across.
▶Will the USDZ open at the right size?
USDZ stores an explicit unit, so the model opens at true size without rescaling.
▶How large a Navisworks file can I convert?
Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.
▶Can I convert USDZ back to Navisworks?
Not here. We read Navisworks and write USDZ, but not the reverse. the universal 3D viewer
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
