Hi Gaston,

I believe you'll need to use Rhino4 for this kind of process.
The Command you're looking for is Flow.

As a Jeweller I've previously used a very similar process to what you're after with my Roland MDX-15 mill.
At the time I was using a "mechanical rotary unit" via a gear on the Mill's Y axis to drive the rotary.
The Y axis length is 101mm, so this meant that all rings had to be "stretched" out flat to fit the 101mm length.

One of the 3DWaxMill Forum Members named Ken Sanders wrote up a basic Tutorial on how to do this with Rhino4.
Hopefully this Tutorial will give you enough info to help achieve similar results for your model.

regards Colin
