This is for wax printing, I cast these into jewelry
How do you make the "wax printing"?
Are you using a 3DSystems rapid prototyping (additive manufacturing) or similar 3D printer?
Is your result an stl file for 3d printing?
I think I would check out Fusion 360 (search Google for free beta) or maybe one of the Autodesk Alias products.
Fusion 360 should be easy to learn, but as it is new I am not aware of the full capabilities.
You should post your question on their forum.
Be sure to provide complete information, including answers to the questions I just asked (stl).
