Hi,guys.
I would like to create the following program.

· Get the largest number from surrounding points
· Go to that point
· Create a geometry from a pointIt is an image like a maze algorithm.
I will attach a reference image below.

Hi,
I’m new with grasshoper and I’m taking the first steps with this “software”.
So, I don’t know if it’s possible to get with grasshoper the direction of extruder when I convert from STL to GCODE.
This video:
It’s possible to see the XYZ movement but how I can get the angle of extruder ?
Thanks a lot.

hi every one
i have a tall building structure and would to do structural analysis with karamba but the results of displacement seems incorrect. by analyze component, displacements are high and by analyze nonlinear WIP component, displacements are too low. i read the manual but i did not understand difference between these two components.
on the other hand when i connect joints to assemble model analize component show errors.
can every one help with these two problems?

Hello, I want to do some physic simulation in kangaroo.
I know how to make a slider mechanism at static trail in kangaroo, like this below:
It works fine.
But the slider won’t follow the trail when the trail’s position has changed (ex. the trail is moved by grab force in kangaroo), like this below:
Is it possible to achieve the goal that the slider mechanism can follow a curvy trail moving by kangaroo force ?

Hi World,
I am having trouble with a C# script in Grasshopper. I keep getting a ‘System.Drawing.Color’ error and I cannot figure out how to fix it?
When I right click on the to “Manage Assemblies” nothing comes up after I click manage assemblies. Any insight would be a massive help!I am trying to pack circles with set radius to represent an image from a mesh, if there is a more effective way to go about this please let me know!
Thank you!

Hi all,
I am new to grasshopper and recently I am looking at one grasshopper script but there is one unknown component inside. The command icon is like this. It has the same icon as “cherry picker” but the inputs and outputs are different. I was wondering if anyone knows what this command is. Thanks for any help in advance!

Hi guys! First of all I’m new with grasshopper. I’m trying to make my last degree project with grasshopper because he requires a parametric solution for the structure. It’s been really great, with alot of new steps every day to understand better the plugin.
Ok so. I can’t really explain why this is happening but I’ll try to be the clearest possible.
I’m creating a 6 vertices surface and I’m trying to subdividing with the isotrim/subsurface option. But everytime i trying to divide, I got this huge 4-side-subdivided-plane that goes beyond my geometry boundary. I guess thats because the U.V. coordinates ara messed up with this non-4-side-plane? I don’t know.
Right now I was trying to subdividing with a surface box and got the same results…
I’m trying to create a structure similar to New trade fair milan by Massimiliano Fuksas.
I’m attaching some example imagens to help the troubleshotting. And I didn’t find any place where I can post this in the grasshopper website forum… If someone can enlighten me so I can move this discussion to the website forum…
ps: Sorry for my English.
Greetings from Brazil! And so much thanks!

Hey!
I’m quite new to grasshopper and python scripting so I’m hoping you could help me whit my problem. I found this: https://www.youtube.com/watch?v=syOnj_QFaEc&t=95s (3d Perlin noise for grasshopper in python script) and I’m wondering if it is possible to generate the minimum distance between outputs(points). If yes is its still going to be Perlin noise? I’m sorry if this question is stupid but like I said I’m veryyyy. However, I need this for my school project.

Hi,
im new to Grasshopper but I’m now trying for days to get a closed mesh as a ring and inflate it without getting peaks on the edges the mesh meets itself (end/beginning).
i tried this with weld and join and weaverbird (mesh from lines) but in weaverbird the outgiven vertices are unusefull sorted in x-direction what is hard to handle with in upcoming worksteps.could someone please help me to get a continous/closed mesh ? or to sort the vertices in Weaverbird by isocurves?

Could you check my rhino file or image below to give me an idea if I can fold this pattern with kangaroo or not? If it is possible, how should I define the naked edges, mountains and valleys? many thanks in advancepattern-for-kangaroo.3dm (685.0 KB)

Hi,
Its the first time I use this forum.
Meanwhile, I have create an untrimmed surface with a height map and I am trying to split it on a 30mm interval so as to produce a file for milling with 30mm thk. wood. However, the split brep component doesn’t work and it shows an error of split did not success.

Hello everyone!
I am trying to make a kind of “weaving” by defining a certain motion to a point using iterations (with Anemone). i am defining this motion within the loop but since i want this movement to happen inside a wall i want to also define the boundaries in which it is going to move. i created a small cluster for this bouncing in the box walls, but it doesn’t seem to be the proper one for this case… so i got a little confused…any ideas?Thank you!
in the definition i included the first vertical movement version and two other versions where i added some random vectors so that the movement can expand more in 3d space…

Hey everyone,
I want to create a mesh of a half circle to play around with in kangaroo like this.
My first way was to draw the geometry in rhino, split the half circle in two quaters and loft each one with the vetrical split line to create surfaces that can be easily meshed with the Mesh Surface component.
Since Rhino 6 I get a invalid mesh out of the Mesh Srf comp but Combine&Clean does it’s job and I get a Mesh (V: 821 F: 800) that works fine in Kangaroo.So I thought I could just create the curve geometry in gh to change the radius easily.
Again same way, but no invalid mesh out of the Mesh Srf comp and I get a Mesh (V: 841 F: 800). I tried it in Kangaroo and it didn’t work so I took a look at the mesh, and noticed that it has 20 interior edges with 0 length and 20 duplicate verticies (for the quaters the 0 length edges are exterior since they are located at the point where vertical line and arc intersect):Since I don’t know how to rebuild the mesh without the 0 length edges/duplicate verticies I tried Mesh Loft and it works like intended.
But I wonder what is the difference between the referenced/internailized and the gh curves that allows this to happen?
I would love to understand what the problem is and how to solve itHere my gh file:

Hello all,
I am attempting to recreate small portion the structural elements of Taichung Opera house by Toyo Ito. I have been following along a video I found to create it, but unfortunately the video is not as thorough as i wouldve liked and the some of the pieces are missing. If anyone could just review the script that i have and see if maybe i made a mistake somewhere and i can do the rest! I just need a nudge in the right direction. also attached is an image of what i eventually will have after completing this small portion. but if there is a more efficient way to get there, than the path ive chosen id love to learn more about it

Hi all
The points that are in the list shown below I get interspersed, ie two points of an armor, the other two points of another armor and so goes; what I want to do is to order all the points that have the same coordinate ‘y1’ in the first indexes, those that have ‘y2’ in the following indexes and so on. How could I get that?
Thank you
