Shape like a branch

Rhino SubD

1

I am planning to make a branch-like Ring with SubD.
It is like the one I drew in the red diagram.

First, a Ring was created using SubD as shown in the figure below.
The two branching SubDs would like to change their shape.

I would like to split it and fill in the holes with Fill to make it look like the red diagram.
However, I cannot get the Brige to work.

Can you please let me know if there is any other way to do this?

best

You need to have the same number of faces on both side of the bridge.

HI @martinsiegrist

Thank you.
I understood that the bridges needed to have the same number of edges, but I were having difficulty matching the edges on both sides.
By the way, is the only way to adjust the gumball to make it a perfect circle?

There’s no perfect circle in SubD. You can get close to a circle by having your edges distributed as evenly as possible.

Hmmm, I see.

By the way, is this sample trimmed or split around this red line?

Are you deleting the bottom half in Box mode?

I duplicated your object and deleted half of the loops on the upper halves.

Second step was closing the openings.

However, there is an easier way to achieve this without having to delete and close anything:

You can create a ring and move it so one side is perpendicular to the XZ plane.

Then move some of the rings on the upper half away from the plane.

Finally mirror the ring with the reflect command.

I don’t think it matters in which mode you delete something. And it would be flat mode, not box mode :slight_smile:

I see!
I can use Reflect well to create a clean shape and make it easier to edit afterwards!
Thank you very much for your kind explanation :slight_smile:
