First of all great Tutorials - keep it up! Secondly I'm stuck at 5:26 because I dont know which bounding box/brep I need to insert in the *Voronoi 3D* component
I searched and looked and it is the last thing of the very first group, the scale note. It goes into a relay node and then into B from the Voronoi note. Sadly it still doesn't work
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"
I know it is already too late, but the voronoi is connected to a relay that is connected to the scale node. I ran into the same problem, you can spot where he connect it to later on in the video. it's very easy to miss, took me an hour to figure it out.
hello...firstly love your videos...thank you much...they are so very helpful. I was actually doing a project using this tutorial of yours, but I am getting "Boolean Intersection set is empty" error and the solid intersection is failing. Can you please help me with that.? Again thank you for all your videos❤❤
I also got the same problem. I put connection from Brep to Breps B and connection from Voronoi 3D to Brep A in Solid Intersection and error disappeared.
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.
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.
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.
i have a qustion "why the Voronoi 3D and Multipipe" is red in grasshopper? Voronoi 3D says 1. At least a single valid point must be supplied Multipipe says 1. Solution exception:points must contain at least 1 point
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?
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).
Hello, do you know why the connection between the voronoi 3D with the solid intersection doesn't work?? the error message is " the booleen intersection set is empty"
I'm having an issue with my model. Not sure if it's because I started with a brep instead of a subd. Everything works up until the multipipe command converting to a mesh body. The multipipe populates but the mesh does not. Any advice?
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.
I've had the same problem! did you found a soultion without using dendro??? I played with all the parameters but the problem is still there. It come out from the "remove unecessary edges" step.
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?
I think i know what your talking about, is it the part where he skips a step, so you end up not knowing where the Voronoi bottom part is connected to. It's connected to the relay that is connected to the scale node. (you can spot it at 10:17, where he zooms in you can see where that connection is connected to). Took me an hour to figure out what I was missing. (total 3 hours)
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
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.
good, but very complicated to use Grassopper... it's a task for a visual programmer, not for the average Rhino user. (it's similar in BLENDER). Playing with Grassopper is not for everyone.
I am stuck at 3:09 solid intersection. It says Boolean intersection set is empty. Also when I click on SubD it doesn’t show the outline of the helmet, just shows the box. Please help
Hi, I know this video is a lil old and I'm just trying to make something like this to make a 3D print but I'm trying to use something that I've designed in solidworks ¿How should do I import the archive?

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?
@@3DBeast Thaks! Also in minute 4:49 how can I test if each point is inside? And in minute 5:24 Voronoi 3D got more connections but theres no explanation about what happened, so maybe you can help me
Finally, figure it out, the "Merge" component's output must switch to the "Flatten" mode to exactly merge two bunch of points together, which allows the "Voronoi 3D" to generate the correct cells.
This would be good except that it goes so fast I have to watch the same section 10 times to try and capture everything that's said in a 10 second clip.
agree, I added "Python 3 Script" and copied the text, renamed the connections to a/b/c, and it shows the script-running error "name 'b' is not defined". When I connect Brep and Voroni to Python, I get "1. Error running script: object of type 'Guid' has no len() [15:1]"
I have a problem with the gh-parallel script: (5:35) I have set input_b of the script to "access list" because "object of type GUID has no len() [16:1]" But then I get this error: "1. Error running script: System.Guid value cannot be converted to System.Collections.Generic.IEnumerable`1[Rhino.Geometry.Brep] in method Rhino.Geometry.Brep[] CreateBooleanIntersection(System.Collections.Generic.IEnumerable`1[Rhino.Geometry.Brep], System.Collections.Generic.IEnumerable`1[Rhino.Geometry.Brep], Double) [16:1]" I double and triple checked, the script is identical to the one shown in the video. Everything else works perfectly.
The error you're seeing typically occurs when the script is expecting a Brep but is receiving something else, Make sure you set the Hint for both inputs to Brep (Right-click on each input, select Hint, and choose Brep)
I feel this is one of the first and only good grasshopper beginner tutorials.
