Help with flow along surface

Rhino Rhino for Windows
1

Hi,

I’m very new rhino! I’m having a bit of trouble with getting an extruded surface to flow along another surface but I keep encountering different errors.

I am trying to create a ring where the pattern can be extracted from the cyclinder to look like the attached picture.

I would appreciate any advice.

Many thanks,
Millie

Hi Millie - to make this work out cleanly, you need to start with the pattern like this:

if I understand whart you want. However you still have the problem ofthe ends meeting up with the closed object faces at meeting point

So that needs to be cleaned up. It is probably best to flow the curves and make the surfaces in place. I’ll see if I can cook up an example.

@Millie_Bradbury - in case this is what you are after -

The curves are flowed then used to split the cylinder. The split out bits are made into the lattice-ring with OffsetSrf > Solid=Yes.

Hi Pascal

Thank so much for your help, that is what I was looking for.

Can I ask how you exactly you flowed the curves so that they joined perfectly?

Hi Mille - I made sure the curves end right at the edge of the base surface, and that they end on the same location along the edge as the other end:

Does that make sense?
