CAD Design of Ring

Design a ring via CAD by very specific criteria. MUST use Rhino or Matrix, and be able to follow instructions very carefully. The ring photographed below will be the first project. The center stone is 7mm. The side stone are 4mm. The accenting stone in the band are 1.2mm and are to be preset with bead. The accent stone are bordered with millegrain beading as the photo shows. The ring band is 1.7mm in width. The ring band is 1mm in depth. MANY additional jobs to follow if this project is completed satisfactorily.
