If you are just outputting toolpaths of a CNC table in 2D you can output true curves. I do it all the time. Set the camera to PP, set the view to TOP, export 3D, choose dwg, in the options set the checkboxes to export only edges, export. The resulting file will be a 2D dwg with true curves.
Search the forum, I’m on my phone now but we have discussed this many times here and you should be able to find detailed instructions.
