# Modeling a curved ring projected to a circular top

I'm trying to model a ring with a special form. On one axis, the sides wider towards the top and at the same time the top part is making an oval like in this drawing:

edit: here is an actual picture of the ring

And Here is my failed attempt:

How can you model a rign like this?

edit: I tryied to scale / move the upper part with proportional edit, but I cannot achieve a smooth result:

• Select all the flat faces at the top of the ring and with Proportional Editing turned on Scale on X

• Select the top flat faces and use "to sphere" this should work and it's a very short way to do it, just make sure you're not using proportional editing. Commented Oct 31, 2019 at 16:00

I have a ring similar with your picture. The lenght is not the same, but the modeling way could work. First I did a structure with circules and arcs what are the edges and following the faces using Grid fill.

I am doing the process step by step to get the pictures:

• Draw the main edges using arcs and circles;

• Do the surface with grid fill. I needed to cut the path of circles to use grid fill;

• We have a simetric part, so we need only 1/4 of body and use mirror to get all ring;

Create a cylinder to get the central hole through boolean operation;

• Use the modifier boolean difference between ring body and cylinder. Apply it;

In edit mode, select the vertices from botton right of ring;

• Using the spin tool, do the botton half of the ring;

• It was added the modifiers edge split and Subdivision surface;
• Do the top surface defining a vertice at center of circle and the edges to border; enter image description here

• This shows a very nice result.. it would be a more useful answer if you illustrated enough of the process to give @denoise a shot at reproducing it? Commented Oct 31, 2019 at 6:24

Your blueprint is not very clear but I've tried something, here it is, step by step, tell me if it's correct.

• it looks very nice! but the sides should be flater. can you explain me al little bit more how did you did this? Commented Oct 22, 2019 at 18:09
• fater? it fits your blueprint, except the top circle but you didn't give any top view, plus I think your blueprint wasn't completely explicit, so it's only a guess... well to do it you need to put the blueprint as background, mirror, follow the shape with some extrude, move, delete, join, merge, etc... ;) Commented Oct 22, 2019 at 18:14
• how did you shaped the top part as a circle? di you joined the circle with the rest of the mesh? Commented Oct 22, 2019 at 18:20
• I first made a square, then created a circle, deleted the square and joined with the rest of the mesh, but there might be other ways. If the top is fatter than what I've done, just move some edges. Commented Oct 22, 2019 at 18:22
