Grasshopper

algorithmic modeling for Rhino

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

Again, you didn't internalize the 'Crv' data for your 'Loft' input, and it doesn't help to open your previously posted Rhino file.

Sorry here it is

cross2.gh is substantially different than cross.gh - cross2.gh has two 'Scale' components in series - why?

Pretty hard to follow what you're trying to accomplish?  And what is the problem now?
