Are you wanting Rhino to create your cut paths? If so that is not possible unless you have Rhinocam. I am currently using a member here at the zone to do all my cam (machine code) and am 100% happy. Are you wanting to section the model becase it is too large for your machine? If that is the problem then yes you can section it either direction or both directions. It will take me a little while to find it and no better than I am with Rhino...I might never find it! I'll try it a little later and will post what I find.
