Conversion from Unigraphics to Fusion 360 is not supported yet :(

Unigraphics is a former name for Siemens NX, an advanced CAD/CAM/CAE software application suite. However, veterans are still using the Unigraphics name.

In 2002, the new version of Siemens Unigraphics, merged with I-DEAS software, was released and called NX, which means "Next Generation". In fact, it was the last version of the software released under the Unigraphics name. All further releases became known as NX. So the addition of I-DEAS functionality to the core code of the Unigraphics has become the basis of the existing NX product line.

Siemens NX / Unigraphics use a .prt extension, which contains 3D CAD parts.

Fusion 360 is a 3D CAD, CAM, CAE cloud-based platform by Autodesk, which connects the development processes of a product. Solid, Surface, T-Spline and Mesh geometry are supported as well as drawing, rendering and 3D-printed output for design validation and documentation. Fusion 360 runs on Windows, Mac OS and in browsers. It is mostly used by students of manufacturing and design spheres.

It is a collaborative platform where users can access each other’s files which shortens design lifecycle. As the app can run either on PC or on the cloud, it can work both with and without internet connection. Data management is built into Fusion.

Autodesk Fusion has a single model environment in which all unique parts and assemblies can be created. It incorporates both direct and parametric control. In Fusion users can make drafts, prepare designs for 3D printing as prototypes or as final parts. Fusion 360 includes integrated Assembly modelling, Motion studies, Rendering and FEA tools to help users analyse design before making it. As document management is built into the platform, files are automatically backed up to the cloud.
