Engagement Ring: Bridging the Band to Basket

[Sam_Sanford]

Hi Fusion 360 community,

My fiance and I are designing her engagement ring together and I am struggling with how to connect the basket to the band in a smooth and seamless way. I tried using lofts, I tried using an extrusion and trimming off parts, but I can't get anything to work. I haven't tried surface tools, but usually those don't work out so well for me, especially the stitch command.

The file is attached, can you take a look and see how you would suggest bridging the gap? The spacing between the basket and the ring is exactly as desired.

Just an idea.  Model attached.

I can think of a dozen ways off the top of my head.  probably best if you sketch what your after so we don't chase our tail

Hi,

Have you actually looked at how a jeweler might actually do it on a real ring? I would just pop down to the

Jewelry shop and have a sticky beak at what they do there. You may find your solution simply through either

straight copying an existing design, or discovering there is only a hand full of ways a jeweler can actually

do it. There is no point re-inventing the wheel, nor coming up with a fancy solution that cannot actually be

done. The Jeweler can also give you advice as he would be keen to make it for you.

Cheers

Andrew

I would follow @laughingcreek's advice. So far in this thread he has by far the most experience with surface and t-spline modeling tools. Sketch the thing (pencil/paper).

I've helped a friend design the jewelry for her business. Almost no shapes are off limit with todays 3D printing technologies. Lost wax casting with the wax form being 3D printed allows very elaborate shapes, as long as structures aren't too delicate.

After looking at John Hackney's version, I came up with a strategy of extruding a new body (rectangle) and the trimming the edges to match curves by using offset and extend surfaces to split the body. Then mirrored and filleted everything. This way the bridge is as thick as possible for strength and the fillets play nicely. Here is my model attached.
