Hi BG,

re:

Yes it could be good for that.

But are you really planning on cutting a helix shape out of wood on your CNC?

Do you maybe have some example images of the types of things that you would like to make?

If it's all in the category of relief/emboss signage type stuff then you're probably better off doing it all in Vectrix.

Even with MoI that's trying to be easier to use than "regular cad", there is still going to be a pretty noticeable jump in complexity from 2.5D work to full 3D CAD + CAM work.

The more that you can give some more details and examples of actual pieces similar to what you want to make would help to give you better information.

Usually stuff like parametrics are used more for design of mechanical parts.
