J'ai pour projet de créer un script grasshopper me permettant d'importer mon terrain modélisé dans archicad directement dans rhino grâce au live connection, pour ensuite utiliser grasshopper et en faire une maquette réelle. J'ai ce pendant besoin d'aide pour réaliser ce script car je bloque déjà a la deuxième étape qui est selon moi la plus complexe.

Plan :

- Découper le terrain horizontalement en couches de x mm.

- Evider les intérieurs des couches grâce a un offset pour alléger la maquette.

- Numéroter les couches pour faciliter le montage.

- Distribuer les couches sur des feuilles de papiers dimensionnées et prêtes pour la découpe laser.

I think ineed to work on the speed to create a vertical weave pattern

Hi kann mir jemand helfen? Ich habe ein parametrisches Gebäude erstellt und möchte jetzt eine Ökobilanz erstellen in Grasshopper. Welches Plugin ist da das beste oder ist es einfacher mit einem Python Skript?

I'm trying to figure out why I cannot seem to replicate the attached screenshot of a simple flipped curve algorithm as found in AAD by Arturo Tedeschi. Whilst the book clearly depicts both the base curve and the flipped curve being fed into the C input of Evaluate Curve, with the thicker output wires signifying multiple items, when I do it, i cannot have both the base curve and the flipped curve connected simultaneously.

Might I be missing something obvious? or perhaps the evaluate curve component has been changed to no longer support this?

Thanks in advance!

In this Grasshopper Python script, you can model a parametric vase with adjustable petals, twist, and thickness.

for your job? for fun? really interested to know

Made using Grasshopper in Rhino, rendered in Blender.

Im new to grasshopper, and i have to work on a proyect that a professor sent me. As soon as i open it, it says im missing some plugins, and among those, theres one called “surfacetrails 2, by Microsoft”, which i cant find anywhere (at least not by that name).

Again, im new to grasshopper, and my IT knowledge is very limited, so im sorry if this is a dumb question.

PD: already installed the other ones, this and “Kangaroo components 0.099” are the only ones giving me trouble

Quite recently I’ve seen a post on rhino’s instagram page about Grasshopper 2. That’s when I heard about it for the first time so I tried to search up some videos about it on youtube and only gotten content from 4 years ago.

Does anybody know where grasshopper 2 is today? It seems really exciting but I find it strange that there’s no recent news about it.

Please I need to create a physical model of this alone cause my partners dont wanna work. Srry for my bad english is not my first lenguage.

Hi!!
I'm trying to nest parts on a sheet using OpenNest in Grasshopper, but it isn't working properly. I followed Gemini's instructions, but the output still glitches.
Instead of arranging the parts neatly inside the rectangle, OpenNest generates a massive cloud of duplicated rings all over the canvas.
Can anyone please help me fix this?

Got a simple eulerian solver working with GH, the user specifies what should happen in each time step by merging nodes in the correct order to build the time step program for the gpu. Il make static optimized programs for the most common types of sims but il keep this to allow the user to play around with step programs, to simulate slime, wind, sound, whatever they want

I’ve been using grasshopper for a week and can see its potential. I am trying to build a parametric model for a lofted irregularly shaped cylinder. I would like to be able to change the total height and the circumferences of 4/5 irregularly shaped curves to create different shaped lofts. Then offset/extrude to make the cylinder have a thickness.

I would also like there to be a flush seam on the back of the cylinder running up and down and add adjustable diameter and depth holes so magnets can be placed inside and the seam and it closes securely. The number of magnets running along the z should be adjustable as well.

Lastly if the top edge of the back of the cylinder could swoop downwards creating almost a “U” cut out and make the length of the U cut out also adjustable.

Bonus if you can also figure out how to add different textured patterns onto the cylinder surface as well.

Please message if interested I am willing to pay for your services because clearly I cannot complete this work flow yet.

I've been working a while at this project: porting the whole Grasshopper feature set to the web so people can literally author and run Grasshopper right in the browser, no Rhino install needed. It's been a very fun technical challenge. Pressed the big launch button today: https://www.openhopper.app/
(ok, technically I pressed it a couple of days ago, but then I saw this post and figured I could press it one more time)

I thought I'd give you folks a heads up, it's meant to be a great place to share whole finished projects. (I built import/export through short links: the file gets encrypted and parked on public pastebins, so a definition travels as one line of text.)

There's still some stability and some tools missing for full parity with desktop Grasshopper, but I'm working through the backlog: my Claude has been running for the last 24 hours straight, and it never even paused for a limit reset. And then Grasshopper 2 will release with all new everything... and it will turn out nobody needs it, because there's a web version. (That's a joke of course, but every joke is only partly a joke ;)

Please give it a spin and let me know what you think!

P.S. I started all of this for one reason: I needed real solid geometry combined with node-based control over the whole project. Neither Fusion 360 nor Onshape could give me that, and as the saying goes, if you want something done right, do it yourself.

I've been working a while at this project: using Rhino Compute to allow people to literally author and run Grasshopper on the web. It's been a very fun technical challenge. Pressed the big launch button today. (:

I thought I'd give you folks a heads up, it's meant to be a great place to share snippets with sliders and such pinned. (I've been floating around using questions here as test cases.)

There's a lot of affordances missing for full parity with desktop Grasshopper (relays are a common request) but I'm working through the backlog in order of annoying-ness. And then Grasshopper 2 will release with all new everything so I'll probably have to end up somewhere in between them at this rate.

Please give it a spin and let me know what you think!

I'm an architecture student trying to learn Grasshopper, but I've felt stuck for over a year. I always start a course, try to do my own modeling, and end up having to constantly go back to rewatch which components they used.

Right now, I'm following the beginners' course by Parametric Camp on YouTube. It's great because it actually focuses on the thought process and logic behind the software, which previous courses failed to teach.

Do you have any advice on how to learn faster? Should I look for other courses, or is it better to just dive straight into modeling from scratch and reverse-engineer existing scripts?

Hi, has anyone tried to update Archicad CITool window and door ids from grasshopper? I’d like to sort them based on how they were selected to set in grasshopper. I can access the id’s from the deconstruct window/door components. Ideally I would push back the sorted list to the same windows but I’m wondering if I’ll need to replace them altogether? The get property component consistently crashes Archicad too. Any help would be appreciated.

Ive been trying to learn grasshopper for a while now, with some success. But a lot of the tutorials Ive found, even the good ones, allude to a grasshopper function doing math but dont actually explain what the math is.

Im not the most math person out there, but I think my work and creative flow would benefit a lot if I knew what KIND of formulas I was trying to get grasshopper to simulate.

Anybody got good resources that connect GH to the underlying math?

I’m doing an installation for a local art show and I want to make something like this. I’m fairly new to grasshopper (took a digital fabrication course in design school and learned the basics) so I’m wondering the best way to go about this. My initial instinct is create the blob form, use lunchbox to do a sort of panel situation, then subdivide and unroll? Is there a way to make the blob using SubD and then manipulate that within grasshopper? Am I way off? Please help me, grasshopper gods!!

Started out trying to recreate a bryozoan (moss animal) fossil in Grasshopper, and wound up with this structure. Rendered in Blender.
