Create a radial tiling

Hello,

I've been using a crv motive, repeated using an rectangular array, so i get a frieze.

If i use an curve array on a circle i get this kind of results

But i'd rather get something like that (roughly made in photoshop)

Is it possible to constrain and deform a crv geometrically as i would like to do here?

Thank you very much

Here was the answer : the bend command

Bend works, but can be hard to control. It's also possible to map curves to a surface via control-points. Works when the target isn't a perfect circle too. If you want to know more, upload your original curves.

Hey,

True, bend is a bit tricky to control.

Here are my geometry. Thanks for ur help!

Also, it doesnt work the same if i set an existing circle in rhino as crv in grasshopper and if i create a circle from grasshopper.

is there a documentation, on what David Rutten mentionned, about map curves to a surface via control-points?

thx!

This will do it...I had a bit of fun with it, so you can get some ideas. The key is you use your base curve to develop a surface...because your module tiles in both the U and V directions, you can subdivide your surface into rectangular patches and map your curves to each.

WOW!!!

This is crazy!

Thats so cool!

I dont know why it makes the shape we have here, ill spend time on it now

THANK YOU!

I just used a unit X instead of a unit Z.

Also, when you bake your 3d shape, you get edges and no surface. is there a way to bake surface/extrusion, so we could eventually 3d print it?

Thx again!

you don't have to move them at all...that was just to introduce a little difference. You could feed the offset curves directly into the loft component and it would sit flat.

I'm not sure how you'd like to 3D print it...there are a lot of curves here, and they are not continuous, so the negative space would have to be integrated as a surface...it's a fairly tricky thing. Do you have a sketch of what you'd like it to look like?

Hey

Actually, i thought that maybe we could use this vase like shape and cut it with the edges we have here in our mapsrf.

i tried to use the same technique to fill a rectangular surface and it doesnt work the same. here are the geometry
