F3D (Fusion 360)

The F3D file format is a CAD format developed by Autodesk primarily for Computer Aided Design (CAD) and Printed Circuit Design (PCB) applications and is the native file format used by the Fusion 360 application. The format was introduced in 2013 and continues to be developed today.

The F3D format itself is proprietary and can be opened with the Fusion 360 application, which is available for both commercial and home users.
