Creating multiple attractor points for a facade in Grasshopper may seem like a complex task, so we tried to simplify it as much as possible in this tutorial where we’re recreating a parametric facade design done by Nuru Karim. The main idea is to create a grid of points that will be used as attractor points and then to create another grid that is divided into rectangular segments. At that point, we will be using the distances from attractor points and the middle points of those rectangles as a way to do the extrusion at the end. We’re giving a definition away for free, so make sure to pick it up and follow along!

Why did you use list items after sorting the values from the flip matrix? And can you explain why isotrim was used with the divide domain? And can you explain again why did we use cull pattern by equating the original distance and the flipped matrix one?

[@HowtoRhino]

Hey Anuj, I will be glad to answer your questions. 1. Divide domain^2 we used here takes the U and V iso curves of the surface and divides it into segments creating domains in both directions. Afterward, we connected the output of the domain with the input "D" of the iso trim, since the component requires domain^2 to get original surface divided into multiple subsurfaces. 2. After sorting the list of all distances at 9:48, we used a list item (with default value 0) to extract the smallest value from the list which is actually closest distance. 3. Each point of the grid has its own set of distances to each attractor point. The set of distances represents each branch of the data tree. In order to find the location of the closest distance in each branch, we use the equation with the list from step 2. Afterward, the pattern from the cull pattern output we applied to the original list in order to get the closest grid points related to a certain attractor in the same data tree branch. If you still have difficulties to figure out how the definition works feel free to contact me at [e-mail] Cheers

amazing, could you maybe do a video about creating a parametric wheel design for cars?

Hey @smallgooddecision, thanks for the suggestion!

[@seechler]

Nice!

[@HowtoRhino]

Thanks Seechler!

[@Dev1nci]

I’m working on something similar but I want there to be a smooth transition between attractors. Nudibranch might have something otherwise it’ll have to be weighted average I think.

[@ferdouskazim9912]

I like your tutorials. I just could not understand the second half of the tutorial. Maybe I am not an advanced user. I hope in the future you could explain the process better with some sketches and diagrams. Anyways, I appreciate the time and energy you guys are investing to impart knowledge.

[@HowtoRhino]

Thanks for the support Ferdous! We try to fit in as much as we can in a time frame of around 20mins for a tutorial (there are some exceptions of course), but in general we don't go too much in depth because that would be quite long and that is the type of content that we have in Rhino for Architects course. Cheers!

[@priyanshajmera8033]

@@HowtoRhino exactly what happened to me, I know rhino quite a bit but this wasn't well explained. I'm sure 15 -20 mins are enough to explain this clearly.

When I flip the matrix I get an error code saying “ all paths may only differ at s single locus “

[@McSneakFreaks]

very nice tutorial! is there a way to apply this process to double-curved surfaces? so the surface will be simplifed by rectangular extrusions based on the normal distance to the surfaces flat base surface?

[@HowtoRhino]

Hi Poldi! Thanks, glad you like it. Yea, so the process of applying this definition to a double-curved surface would not be the same. In that case, you couldn't use the grid component, but would rather be using some other techniques like isotrim component and then doing the normal vector extrusion for each face.

[@tahacherkaoui3030]

nice

[@HowtoRhino]

Thanks Taha!

[@vigneshrajan5614]

Can you help me do this for a curve ? Not a straight horizontal line. I’ve tried it with a curve and set its point but when I do the rectangular grid it goes off in a straight line instead of following the curve. I’m a beginner.

[@gerardolimonchi9545]

Buenísimo 👌

[@HowtoRhino]

Thanks Gerardo!

[@federicomhff8915]

It would be great if you use bifocals plugin. That makes easier to follow the definitions. Bye

[@HowtoRhino]

Hey Federico, yes, thanks for your suggestion. If you get the definition, when you open it, you will see that there is bifocals inside. Just let us know where to send you the definition using the first link in the description and you'll receive it in your inbox. Cheers!

[@tadavis]

Nice video. Be helpful if you could use bifocals as you go.

[@HowtoRhino]

Thanks Tad! Bifocals is included in the definition that you can get from the first link in the description :)

when ı put flip matrix, it shows me all paths may only differ at single locus.What can ı do

Thanks Liam!

[@kiontathomas3370]

How do I fix my grid if it’s only going along the X and y plane. I’m trying to get it to go along the z plane

[@HowtoRhino]

You need to define the plane where the grid will be located. By default is set to XY-plane, but you can simply plug another plane in corresponding input

[@maxboerman3929]

Very clear and smooth explanation, great job!

[@HowtoRhino]

Thanks Max!
