What is a .F3Z file?
F3Z is the archive Autodesk Fusion 360 exports when a design references other components - one package bundling the main design and every linked part. Analyser reads the bundled document metadata and shows the rendered preview inside.
- Did you know
- The F3Z archive exists so a Fusion assembly that links external components can be shared as a single self-contained file.
- An F3Z bundles an assembly’s F3D along with every component, sub-assembly and reference it depends on.
- Fusion 360 designs use ShapeManager, a kernel derived from ACIS, so an F3Z carries full parametric construction history.
- What Analyser shows you
- Open an Autodesk Fusion 360 design (.f3d) or archive (.f3z) and read what it holds: the document type (part, assembly, drawing or sheet metal), the Fusion document version, the number of solid bodies and embedded appearance assets, and the thumbnail Fusion rendered into the file - shown as the model. The editable geometry is stored as Autodesk ShapeManager BREP, a proprietary format that cannot be rebuilt in the browser, so export to STL, OBJ, STEP or 3MF for the full 3D viewer.
- Depth of analysis
- .F3Z is a partial-analysis format: Analyser opens it and shows the embedded preview or thumbnail and the metadata it can read, but the real editable content stays in the application's proprietary format and is not reconstructed in the browser. Formats with a complete viewer are marked "Full" on the formats page.
- Open a .F3Z file
- Drag a .F3Z file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
