Repartition point on a 3D complex surface

[charlene.pinel (Charliie Pi)]

Hi,

I need to have a proper repartition point on this surface but I don’t know how to do it with this shape.

I would like that points are on the blue curve is it possible ? And every sphere with the same distance

Thanks a lot

Is it ok ?

[Ali_Najmaei]

Your srf is not internalized .although there is an internalized one beside it

Sorry I did

Hi Charlie
I’m still not sure what your request is . Are you looking for something like this ??
please be more specific

Hello

See this thread, it is a good one for a nice repartition

"perfect" grid with nice boundary

Hi, this is more of a open question/challenge… A lot of products, parts or even architecture have features where holes are arranged in some kind of grid. Think of venting holes, speaker grill, showerheads… I find it very hard to cover non-rectangular shapes with nicely spaced points, a nice edge and some kind of order. Take this superellipse: [image] You could do circle packing – but It tends to have “holes” in the arrangement of the points; also it is a bit chaotic; [image] You could …

Yes the shape is ok with the big radius
I would like to put a proper repartition in this complex shape. On the picture you can see I have too much point on the same place

[charlene.pinel (Charliie Pi)]

Thanks ! But it’s not a 2D surface

I’m thinking of a more accurate way , I’m gonna try that

Thank you very much !
Yes I try this but I don’t want to see the step

I would like to read a line all around the shape

You can use Kangaroo, there are lots of example on this forum.

First slider gives a certain number of sphere then you move up the radius of sphere to make Kangaroo work. And last on the right is just for the radius of spheres.

Thank you ! I don’t know Kangaroo I will read some topic on that

If you wanna extract surface points like they are aligned, I guess the steps are inevitable . I think if look at this , you get what I mean :

@laurent_delrieu way is the best for this .

I would just create a second surface, create a grid on it, and then project/cut the points. You can freely move the surface until you find a good cut. Doesn’t even require GH, works with history as well.
The Kangaroo solution looks nice, but I guess the center is a bit odd. Such solution were often rejected. In my experience, the solution with most equal distribution and a clean cut looks best. Occasionally, I manually transformed some points the get a better outline. If you are also responsible for the surfaces, I would also consider slight variations to the boundary if necessary.
