F3D is a design file from Autodesk Fusion 360. Created and opened by Fusion 360. Fusion 360 launched in 2013 as a cloud-based, all-in-one CAD/CAM tool. An F3D is built on Autodesk’s ShapeManager kernel and preserves the full parametric Timeline of how the design was constructed. Each save of a cloud F3D creates a new version on Autodesk’s servers, letting you roll back the design at any time.

How do I open a .F3D file?

Drop a .F3D file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. 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.

Can I open a .F3D file online for free?

Yes. Analyser is a free online .F3D opener and viewer that runs entirely in your browser - your .F3D file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.
