Good timing, I love your videos bro. Keep up the great work 😁

Best Tutorial on youtube!!!!!!!!

I have this a s a hobby, so well explained!!! Better then the most others.

[@peterlaverty9397]

Fantastic tutorial. I see in your final render there are some deformations. Also can the mesh be closed for 3D printing? Did you 3D print the red one at the start of the video? Thanks again.

Super helpful, thank you!

Is there any way to get the mesh in a way, so one can further work with it? Like cutting it with a nurbs volume? Thx

[@Jp-wp6vf]

Hey, thanks for the tutorial. Unfortunately, you skipped a step, which means it no longer works for me. You skip the part where you connect Voronoi B(5:51). You can't see or understand what you've connected it to. Unfortunately, I get the message for Solid Intersection: "Boolean Intersection set is empty"

[@julesmoizan8893]

So I don’t know if it is a hardware or software issue but once I get to the voronoi 3D part it just lags like crazy, takes a solid 5 minutes of loading once I’m at the merge component and I put it in the voronoi 3D. I have a Ryzen 7 4000 series with an rtx 3050, maybe it’s not optimised enough for grasshopper although I usually have no problems using other softwares like blender, clo or even rhino in general.
By the way great video, the explanations are really well done.

[@lpjunction]

This is an interesting way to make carbon fibre structures.
Say making bicycle parts.
First 3d print the swiss cheese structure, then poke in long straw in either the x-axis, y-axis etc. or even in rings like a coil.
Then put in the carbon fiber in the straw. Next pull out the straw but leave the carbon fiber remain in the cheese.
Repeat the process to insert more fiber until the structure is full.
The final process is to impregnate the cheese with resin.
Such structure should be stronger than other methods.

Basic question - I have a stitched bumper in step format in Rhino and it is shown as ' 1 open poly surface's in rhino command window. Not able to 'set as one sub D' . Am I missing any conversion for subD input before starting?

[@mayteidarraga58]

select the surface in rhino and type tosubd, that should make a copy of the surface and convert it as a subd

[@micheledicarlo1217]

Hi all, I need some help: I followed the tutorial, but I found that there are unjoined parts of the voronoi. This causes an open mesh. How can be done to eliminate the tubes that do not join?

[@kummer45]

Is there a way that I can organize that lattice without using voronoi cells. Of course the answer i the classical lunch box tools or reparametrization for even surface subdivisions. Are there any other strategy for the same voronoi cells but organized? I'll work with the classical gradient triangulations. :P
Besides this is example opens the pandora box to more complex structural systems that are organized and those that are randomized. Optimization may come later. As usual, 3D beast being 3D beast. :P

[@3DBeast]

Yes, indeed! You can experiment with the point placements. The randomness comes from the randomly generated points. You can try out an organized point grid for a more structured result.

...I don't know if someone is still stuck on "Boolean Intersection set is empty"...I've join Voronoi 3d into Brep A and Brep into Brep B and it works!

[@user-gn3uv3wf8s]

I am enjoying the lecture.
I did the same thing as before with the basic subd box object of Rhino, but there is an error in solid intersection. I don't know why, could you please tell me?

[@3DBeast]

Glad you enjoyed it, if you get intersection results while getting an Orange Warning, leave it and proceed to the next process. It will be fixed after the Point filter process. But if you don't get any intersection, possibly, you could try out flipping the brep (in case the face flipped).

For all stuck at ,,BOOLEAN INTERSECTION'' error quote ,,Boolean intersection set is empty''. U need to put G output of the ,,SCALE'' component of the Bounding box set to B input in BOOLEAN INTERSECTION''. That should solve the problem.
