Using auto CAD directly to run Egg-Bot

I have been working with the egg-bot for a while now.  Getting into more advanced designs I have began designing my eggs in CAD but cannot seem to transfer these files to Inkscape files without the resolution depleting.  Is there a way to draw these high resolution images in Inkscape?  (Something more like the Mona Lisa file that was given under the examples.)  Or is there a way to draw the designs directly from Auto CAD.  

Thanks,

Liam
