What is a .F3Z file?
F3Z is a Fusion 360 archive bundling a design with everything it references. Created by Fusion 360.
- Did you know
- Autodesk offers Fusion 360 free for personal hobbyist use, which has made its files a fixture of the maker and 3D-printing community.
- 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 reads
- Identify CAD files and read header metadata: AutoCAD DWG (DXF now opens as a 2D drawing preview - see Diagrams), SolidWorks (SLDPRT, SLDASM, plus .sldreg Settings Wizard backups - release year, settings groups and the saved registry keys - and SOLIDWORKS Visualize .svap appearances and .svpj projects, opened as the ZIP packages they are), Fusion 360 (F3D), Inventor (IPT, IAM), Rhino (3DM) and Grasshopper (GH, GHX), SketchUp (SKP), 3ds Max, Cinema 4D, Houdini, ZBrush, Maya, CATIA, Eagle, and KiCad.
- Depth of analysis
- .F3Z is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full 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 is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
