Bulbous ring question

Hi All,

I had help from the forum creating this bulbous ring in the past, thank you to all who contributed.

I'm now trying to set a gemstone with a chamfered bezel set into the ring.

Could someone please explain how I would go about getting the circled areas of the ring to
meet the flat edges of the bezel?

Thanks in advance!
Gunter

For strictly answer to your quetion
"getting the circled areas of the ring to
meet the flat edges of the bezel?"

Select the Circle Plane
Trim it by the perimeter of the Gem! ;)

But not sure that is the reality! :)

If you want a real volume make Booelan Diff between the differents parts!

A cool habit is to name each part for an more easy selection!

Hi Pilou,

Thank you for your reply :)

Yes, you're right, I think a Boolean difference is what I'm trying to achieve but I get this odd result:




Any idea what I'm going wrong? I'm trying to create a ring where the top of it seemlessly blends into the rectangular bezel.

Thanks!

Each part must be themself a solid!

And for an easy boolean operation it's better if pieces are frankly interpenetrated and not face to face!

Hi,

It's not easy...
Your ring doesn't have "a table" to place your stone.

You could cheat with this problem to soft the transition between your two parts.
I send a proposition which is a blending between a cutted version of the ring and the stone part.


But I think, the problem is the type of bulby you done first which is very large in height and width.
I think it will be not confortable to wear it.
See the red arrows on illustration, those parts are too big, my own opinion.

Hi Phiro,

Thank you for your input.

For the shank of the ring, I completely agree, it looks way too bulky and I can thin them down.

Could I ask though, how did you blend the top to the bezel, that looks fantastic!

Thank you in advance.

Gunter

It's a tuning and not so fast process...

I cuted the top of the ring to have a bigger base. Next, I deleted the top face.
With your bezel I took its base to have the octogonal curve.
On this curve I made a ReconstructCurve (10 or 12 points if I remember) to have a seamless curve.
With this curve I do a plane with the "Planar" function. I do it the use later the blend function.
Because of the initial Process used to do the ring, the top of the ring have 4 edges.
So I cuted the edge of the top planar to have 4 edges too.
To do this I used the trimming function (I used trim points to do it)
Now with 4 edges on the top of ring and 4 edges on the planar, I use the Blend function to have the 4 surfaces.
This gives us a soft transition between the planar and ring.
Join all and your ring become a solid...
You can next tune the size and the place of the bezel and the stone to have something as you wanted.


Have a nice day and fun modeling...
