The F3D format is a purpose-built file format created by Autodesk for use with their Fusion 360 Computer Aided Design (CAD) software. Fusion 360 is popular for use in various engineering and manufacturing sectors, with the format continuing to evolve with new features added with each new release.
Contained within an F3D file is the 3D object, along with its associate elements. These are defined in a manner that incorporates a complete history of the object, allowing adjustments to be made to earlier parts of the object while maintaining the final valid 3D model.
As F3D files can only be opened using Fusion 360, support for opening these files with other software is limited. Fusion 360 does offer export options for STEP, STL, and other popular formats, meaning F3D files can be indirectly converted to other formats and consumed by other CAD applications relatively easily.

The BLEND file extension is the native 3D modelling file format of the ever-popular Blender 3D modelling software. The Blender format originally came into existence in late 1994 and has since evolved into the advanced 3D format we have today.
The format stores complex 3D mesh data along with textures, animations, lighting, and other information related to 3D scene rendering. The format is popular among those creating 3D videogame graphics and animation sequences due to its advanced features and ease of use.
Along with Blender, BLEND files can also be imported into other popular 3D editing software. The open-source nature of the format allows third-party plugins and scripts to be created to run within the Blender editing environment and extend the format's capabilities.
