Voronoi (3D) Ring

Hello, I am new in Grasshopper so I use a lot of tutorials from the web. Today I tried to create voronoi ring but got this on the screenshot.
Where are the mistakes? I know this question sounds lame.

Many thanks in advance.

And also I found this grasshopper tutorial photo and couldn’t sum-up what are the steps.

Have a try dendro plugin.


Thanks for your time. I don’t know what did I do wrong but it says ‘1. Input parameter Curve Radius failed to collect data’
Here’s the screenshot. Please help whenever you have time.
Thanks in advance

Well… You don’t have anything plugged into curve radius. :smiley:

Post your file, The issue seems to be with your curves (the wire is orange, what does the data coming out look like).

Internalize geometry so we can look at it.

See number 3. How to ask effective questions

And you MUST put a radius that is 2 or 3 times bigger than the voxel size !!!

Your Brep and cells don’t intersect, what do you expect to happen?

Change scale factor (F input of scale) to something like 1.1 (so it is bigger) rather than its default 0.5. @HS_Kim probably changed the factor internally so it is not in his screenshot.

Now it has another warning. :frowning:

Just out of curiosity, are you a native english speaker? If not it is ok, just curious because in English the messages are pretty self explanatory. (Also @laurent_delrieu told you this two times). Radius must be atleast 33% bigger than voxel size. What else could that mean besides what it means?

Your voxel size is 0.10, your radius is 0.08. Is 0.08 atleast 33% bigger than 0.10? :smiley:

Got it. I am native English speaker. I’m not Grasshopper native speaker. The last message helped I guess. Thank you very much.


And if you want some nice rounding on intersection you could use Polyline smoothing

Without smoothing
