Hi Jonah,

You made a good point about tracing a curve...it will not produce the exact same geometry, In my example, I was kind of sloppy..the curves don't match very well.

In Rhino, there will always be some deviation from the original if you match curves with "curvature" or "tangency" and merge or join them, or if you rebuild a segmented curve into a continuous curve, but depending on the number of control points you can live with, it's usually a very negligible deviation.

If you trace a segmented curve with enough control points in MoI, it will be, ( as they say) " close enough for government work" or good enough for jewelry design, in my case. :-)
