Extract voronoi border

Hello,

I probably have a small problem for most of you, but I can’t solve it.

I only need the outer curve of the green Voronoi structure marked in red.

Maybe you can help
I would be very grateful to you

kind regards

okay, well… I didn’t expect that, my journey was way too complicated.

Thank you :slight_smile:

The extrusion and sort list are unnecessary distractions.

You could have used Pop2D and extruded only the cells you cull. Like this:

P.S. Or use Average instead of Sort List:

It’s always fascinating how many possibilities there are :slight_smile:

I now want to scale the width of the curve and then connect it to the unscaled curve with a mesh so that I can have a long, smooth transition into the flat area.

I would like to give you the whole definition, maybe you can understand my idea better and can also help me and show possible variants so that I can understand the whole thing better

You probably want Offset Curve since scale won’t affect “width” of a curve. But you didn’t internalize your curve and I don’t have your plugins… and you didn’t follow any of my advice so maybe you aren’t talking to me anyway?

border…

ohha, I see I uploaded the old file. I’m sorry, it was probably a bit late in the evening yesterday.

“pop2D” definitely makes more sense, but if I use “Average” then I no longer have the option to determine the number of cells along the line.

Thanks, “offset curve” is exactly what I was looking for

My current goal is for the outermost curve of the outermost cells to move further away from the whole so that I have a, I would say more organic transition into the flat.
Unfortunately I can’t get an area created between the 2 curves, traced in the picture with blue lines, which I can then connect with the ones that have already been created

In the end it should be a kind of rivertable that I will mill with my CNC machine.

By the way, the plugins I use here are purely for visual purposes and not relevant to the whole thing

Here is the correct file again

This file has a ‘Crv’ param that is not internalized. I said that yesterday :bangbang: :interrobang:

P.S. I used the internalized curve from voronoi boarder_2024Oct16b.gh (one of the files I posted yesterday) so I can see what you are doing but I’ve lost interest in trying to figure out what you want now. I really don’t care.

yes, you mentioned that yesterday

Please tell me how I should do it correctly,
I right-clicked on the crv components and clicked internalize data at the bottom and selected the corresponding curve in rhino

See the P.S. I added to my previous post.

I’m sorry, I wasn’t aware of the crv component’s internalize.
In any case, thank you very much for your time and your help, I really appreciate it
