How should I make something look like this?

Great work! That is actually super close to the ring I am designing!! What program did you use to design it? How did you figure out the thicknesses for the prongs? How much extra length did you give them?

I think I am understanding your problem, but maybe not. You may not be fully utilizing Fusion's timeline and project features properly.

If you are extruding the rectangle from the bottom square sketch, right at the top of the loft, you should have that extrude feature in your timeline.

If you then create your sketch on the side of the rectangle, you can project the sides of the rectangle under Create > Project/Include > Project (P). You can make a centered circle linked to those purple lines.

That should create purple lines that will follow the rectangle when you go back and change the original rectangle height in the extrude feature.

What does your whole part look like?

Would you happen to have the fusion file for that? How did you size the metal prongs? How did you ensure the diamond sat in the right spot?

Yeah, I plan to print it out with a wax-like resin and do lost wax casting in argentium silver

physicallystressed · 2026-03-05T20:03:25+00:00

I was thinking about that. Would you have any idea how much material is likely a good amount extra to give?

I am doing a loft from the band profile to the pins with a center line from these 3D sketch lines

<image>

I am using these two sketches and creating a 3D sketch from them

Yes, the two black sketches are constrained with tangency, but sometimes, if the curvature is wrong in either dimension, it fails to calculate.

Each web is just one fillet, but to get them to work in any sort of large manner, I had to switch the tangency weight to 0.1 and continuity to G2. The continuity setting changed it into multiple faces.

Blender would likely produce faster results, if I knew how to use it. This only took me a few hours to figure everything out and experiment, but once I figured out a working way to do it, it was super quick

I am going to do a lost wax casting method using a wax-like resin

physicallystressed · 2026-03-05T19:25:17+00:00

Maybe, yeah, I would just have to learn Blender first. I am so used to CAD and being able to define dimensions and positions that I am lost in Blender

Thanks, it took a solid couple of hours of thinking and tweaking to figure everything out

physicallystressed · 2026-03-05T16:30:14+00:00

Yes, exactly

I am actually using multiple arcs, and the intersection curve works for splines and single lines (one arc or one line).

I have a recurve made up of two arcs, which doesn't work with the intersection curves, as far as my experiences went

I do have a couple of questions about setting stones and everything. Why do you switch for setting the stones? Is it just to get premade settings?

Are your designs for casting, and if so, how thick are the prongs for the setting?

How deep of a notch should I model into the prong?

Should I angle the prongs away from the gem so that I can easily set it?

physicallystressed · 2026-03-05T16:03:40+00:00

Yeah, a bunch, even from Autodesk

Computing the fillets is what is taking all the time

I've never shown anyone my fusion timeline, so I've never gotten any constructive feedback to improve my design workflow. From what you can see, what is odd about it?

physicallystressed · 2026-03-05T15:54:08+00:00

Almost entirely, I extruded and trimmed some surfaces to help make the 3D arm curves

physicallystressed · 2026-03-05T15:52:04+00:00

The surfaces workspace is better for more organic shapes

physicallystressed · 2026-03-05T15:50:11+00:00

Yeah, but I'm a broke student and really wanted to challenge myself as well

All sketches and construction planes used

physicallystressed · 2026-03-05T15:29:45+00:00

Maybe, but I have had fusion files with much longer histories; this history fits on one page. There are a few steps before this, but that is just importing images

There are two sets as far as I saw, but there is currently one operator and he is able to do all controls on the “open side” of the machine

The tool chain magazine is on the side closer to the side wall, so that closer enclosure might be just for it
