Rhino is actively developing a plugin focused on SVG exports for Origin: TunaHalf
Here is the thread covering the installation process and usage.
Be sure to join the discussion, share examples that need troubleshooting and help shape the development of the plugin.

Note that SVG's exported from Rhino3D may not work perfectly with Origin--to improve your experience we recommend running all Shapr3D SVGs through Shaper Studio to ensure they're place properly and edit the paths for cut type, depth, bit size, etc.
