Voronoi cell joint

[freesheida1984]

Hello,

I have a question about editing the joints of the Voronoi cell in the attached file. I want to create this structure, but the connections and joints are not suitable. How can I fix this installation?
also for every seed number I want to have proper join and connection.

thank you in advance

the connections and joints are not suitable

Can you explain why they are not suitable? What are the conditions for a suitable connection?

[freesheida1984]

hi, since I want to print it in a large scale and I want to have a robust structure, in my model if you see the whole structure there are some separation between elements.

[adel.albloushi]

Are you using standard pipe?
Try multipipe

[freesheida1984]

I use this component now, it looks better but for a few joint there are weird shape, I attach in this command box.

How to apply Voronoi lattice structure on any geometry in Grasshopper

Towards the middle he explains how to deal with that

The spikes occur when vertices are to close together. This needs to be cleaned up.

One approach:

GH multipipe give spikes when there are sharp angle

For every curve, find the points which are within a distance twice the radius of the multipipe. Split the lines at those points and use all other points as FixPoints in the topologizer. This should eliminate spikes. [image] [image] topology_optimization.gh (46.0 KB) In a second step, lines shorter than maybe 1.5 - 2 could be stretched / scaled with a Kangaroo definition.

in updated version of Topologizer there is no output for Line, it jest gives the points of curve, the approach must be a little different, I was unable to edit based on your shared file.

I edit my file following this video, but I don’t know how I adjust the distance between points, since in this video he used SubD while in my file I use box and populate 3d, if you have any hints, I will appreciate it. also there is separation

between elements in structure.

In the video, watch from minute 7

@freesheida1984

in this video he used SubD

It doesn’t matter.

[freesheida1984]

if you check my file in my last reply, you can see that I applied all the process in the video from minute 7, but there is separation between some elements yet.

replacing these mesh components with Deconstruct Brep makes the missing connections pop-up

I didn’t investigate the reason for that, just followed the video instructions

thank you so much, my problem is fixed
much appreciated

I’m not aware of an update for the topologizer.gha

Where did you download it from?

I guess this one

About the speed of Topologizer

Hi @Quan_Li Certainly Topologizer is doing a lot more than needed for this sort of use. My main original motivation for making it was wanting to turn the results from ‘woolly threads’/‘edge bundling’ type simulations into clean graphs that could be thickened. For that it needed to not only combine nearby points, but also find intersections between crossing and nearly overlapping but non-duplicate sets of line segments etc. All of which adds a lot to the calculation time.

This is my final file, I could edit the whole studs
and remove separation among them. Since I want to print this structure with 3d-printers, I want to remove some part of structure as shown in the picture, is it possible to remove these parts?
I’d like to simplify the design for easier printing.

increase the value of that slider until you’ve eliminated all the small faces

much appreciated. it works
