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

Onshape is a CAD software system, delivered via internet. It is focused on mechanical CAD and is used for product and machinery design in many industries, such as electronics, machinery, medical devices, 3D printing, machine parts and industrial equipment.

It makes use of cloud computing, with computer-intensive processing and rendering performed on Internet-based servers. Users are able to interact with the system via a web browser or the iOS and Android apps.

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.
