Can anyone help me to model this ring?
I’ve tried and got this

What tutorials have you done to familiarize yourself with Rhino surface modeling?
Hi Aram, This might give you some ideas on how to do it. I fyou don`t understand any of the commands I write then you should do the basic tutorials that came with Rhino before trying something like this…
Draw the side shape of your ring.
Extrude it out solid.
Cage edit it to shape.
Cut it into quarters deleting 3.
Offset your surfaces to create the recess.
Next create a side profile and split and join up using loft, sweep etc
Use quad symmetry to recreate the ring, join up and then boolean away the parts out of the centre.
The chamfer that edge and you can add in the other details.

@sochin - to pick a nit, with a shape like this it seems overkill to cage edit - I’d trim with curves or extrusions that have the transverse shape - the resulting object will have much cleaner surfaces and probably much better edges.

@pascal You are of course correct. LOL nowdays I would actually just make this in t-splines. Hopefully this gets him started.
Many tutorials. I modeled quite some rings:
Engagement ring.3dm (7.8 MB)
first with diamond.3dm (1.3 MB)
Ring with Gemstones.3dm (344.1 KB)
Decorative Top Elements.3dm (193.0 KB)
And also Jean Gorospe’s Cocktail ring. That file is to big for uploading.
I got bug - naked edge. I couldn’t fix it.

I offset on surface duplicate edges. The top one estrude with gumball to planar srf. Then split them.

Can you help me toadd prongs and diamond properly. Idownloaded gemstones file from grabcad.com but gems from that file didn’t snaped - I can’t move stone.

Hi Aram - the stones are mesh objects, you’ll have to use the Vertex osnap to position these.

Thanks Pascal. I didn’t know that. Is there “central vertex” or anything like that? How can I use Move or Orient command for mesh object?
@Aram If you are going to make this in vanilla Rhino then there are two free tools that will help you a lot. First is @pascal Distribute script. You can download it from this page. Scroll down through the list to find it.

For the diamonds in the top of that ring just place one on an outer side, mirror to the other, fill in the gap in between duplicating with dragging the gumball and then run distribute on them all. I find this faster than doing arrays in straight lines.
The second is this tool which I can no longer live without and am very grateful for @Jarek for making . Get your head around this and it is a wonderful tool for jewellery.

Did you make it eventually? Im curious
Wait, why would cage edit be an overkill? I am not completly following, care to explain?
@ShynnSup I know this question was to @Pascal but he was referring to my post with those comments about “cageEdit being overkill”.
At the time when Pascal commented I had accidentally hit submit post when I was only half way finished writing and it looked like I was saying to do the whole lot in cageEdit…which I agree would be overkill.
Rather than explain my premature posting I just finished the post (in the manner Pascal recommends I think) and moved on.
As I said in a reply to Pascal later…I would indeed now make something like this entirely in t-splines. Very quick with symmetry and no filleting required when you finish. Merry Christmas.
