Hi Khalil,

I actually made those videos a while back. I have a small cnc machine I use for hobby and have just as much fun making the designs as cutting them. I use Moi for a lot things with it, but as the others have said orgranic shapes like the one you put up are better done in a quad modelor. It just a lot easier to to tweak the shape out than to draw the profile. Right now I am carving and designing a bunch of different fly boxes for fly fishing. I used Moi to make the basic box to exact size then made the patterns for the top in modo and zbrush. Moi does have a ton uses for me with cnc, but it is not the only tool.

I have a machine and worked on and needs some work Decoration and ornaments found This Albornakj easy but you Mkhti but I think I'm where some people work like these are decorations on the program moi

I would agree with the others that the best way to approach this may not be with a CAD tool but a polygon modeler.

However, as there is a need to have this kind of work in nurbs/CAD format for CNC machining, there are ways to convert polys to nurbs.
