Ring in Rhino 7

[Marcel_Laci]

Hi guys,

i was wondering, how could I create this type of ring in Rhino. I was trying to do it with the twist command, which works great, but I dont know how to made the middle part wider, without making the wires larger.

Any help would be appreciated

Kind regards Marcel

It is made in Grasshopper.
The .gh definition has small problems, but I hope the idea is conveyed.

Here’s my approach with three entwined helices:

check out some further references - to have a nice optic and nice feeling / “ergonomics” the inner surface will not be a helix.

check out “croissant ring” or “twisted ring”.

I think this is a quite nice exercise for lost wax sculpting / modelling.
(real world, hand crafted…)

without learning grasshopper - this should be quite simple with flowalongSrf.
… search this forum for flowalongsrf ring jewellery or other keywords… you ll find a lot of starting-points.

kind regards -tom

Removed a bit too much material but it works fine with ShrinkWrap…
