Hi Dzeko, you might try saving to PDF, AI, or DXF formats, those will generate a 2D drawing using edges and silhouettes of the NURBS model.

For rendering programs the standard way for renderers to work is to convert surfaces into triangles and then render the triangles. With a renderer like that you might be able to get a better looking wireframe though by exporting out from MoI using N-gons instead of triangles which will preserve more of the original edge structure of your object, and also if you export with "Weld vertices along edges" turned off some renderers have a "toon" mode which can put outlines on the open edges which will correspond to the original edges in your NURBS model so that's another possibility.
