Has anyone tried this?
1. Draw with autocad solids.
2. Use MDT to convert a solid face to a surface
3. Use MDT to create flow-wires offset from the surface (by the radius of the ball end mill you intend to use)
4. connect the flow wires
5. export the point data of the 3dpoly line and use for a cnc program.
I have some nice shapes programmed with this method.
