Conversion from Inventor to Siemens NX is not supported yet :(

Autodesk Inventor is a CAD application for 3D mechanical design, simulation, visualization and documentation. It is built on ShapeManager, geometric modeling kernel by Autodesk.

Inventor enables 2D and 3D data integration in a single environment, virtually representing the final product. It allows users to check the form, fit, and functions of the product before it is built. The application provides strong parametric, direct edit and freeform modeling tools as well as multi-CAD translation abilities.

NX, also known as Unigraphics is an advanced CAD, CAM, CAE application which is owned by Siemens PLM Software. It is commonly used for design, engineering analysis and manufacturing. NX is built on Parasolid and runs on Linux, Microsoft Windows, and MacOS.

On the CAD level UX provides parametric solid modeling, freeform surface modeling, reverse engineering, styling, engineering drawing, PMI, reporting and analysis, knowledge-based engineering, sheet metal design, assembly modeling, routing for wiring and piping. In CAE key functions are stress analysis, kinematics processes, CFD and thermal analysis. As for the CAM level, the main function is numeric control programming.
