Curve middle line

[jdsilvapereira]

Hi,

I need to make something like this:

But not limited to a fixed distance between lines (offset)…

So, I need to infill a area of closed line and divide the area to create X number of lines like the image, and create something like a “sin”

Any idea ?

Similar to this (this shape is perfect, but is limited to offset):

How to create a sine wave from a line or spline?

Peter, What I’m trying to accomplish is to create an architectural wall with that "Corrugated “infill” This is what is used in printing concrete walls. So I’m trying to figure out the workflow to go from a perimeter wall to a wall outline with the corrugation. That would be extruded and sliced to 3D print. Here is a real world example: [mur-sinusoide-22] [Yaroslav-3D-Printed-House-3D-Today31] [house-3d-printed-shanghai-4]

Try to use pufferfish plugin’s Net On Surface component.

I need to update that, I guess he wants to be able to have a offset distance between them for the extrusion thickness.

Hi,

Here’s a ‘retarded’ way of doing it:

WOW… you are amizing I will test …thanks.

Here’s a ‘retarded’ way of doing it

ok.

If I duplicate the RED curve with negative formula (-y*sin(x) - GREEN curve) I get what I need but I think that is not the best solution:

It’s possible to create a “flip-flop” (+ / - / + / - etc…) to obtain the touch between axis ?

for sure, but I don’t want to do that

keep it retarded via mirror

[edit] sorry didn’t pay attention to color-coding

@jdsilvapereira

I think that is not the best solution:

how dare you!

I remember dealing with a concrete printer, just wanted to give you some play

here domain is kept fixed

ahha … I’m talking about “my solution” (my changes in your solution) , not yours

Thanks again…

[René_Corella]

yes

you’re welcome! I hope it helps!

Hi,

I tested the system but I have a problem. I can not cross lines

Only like:

[Michael_Pryor (ekim)]

Did you try the Pufferfish component?

[jdsilvapereira]

No, because I need to make all the system without any component… only native code.

Idea is to use offset from curves…

What do you think ?

[René_Corella]

I am sorry @jdsilvapereira, I am not following you at the moment - The initial file that was shared with you had that, didn’t it?

I mean this

then you wanted to invert the sine curve and I suggested mirroring, simply that - the curves were never crossing and if you don’t preview the ones mirrored then you’re left with non-crossing curves -

so what do you want?

Clarity is important as this is the first time you write ‘you cannot have them crossing’ and also that ‘you can’t use plugins’ after others kindly suggested pufferfish earlier.

[Michael_Pryor (ekim)]

I suggest something like this, so you don’t have intersecting paths and also you can define distance between bumps for material thickness.

Hi,

Yeah, it’s like your example:

But I test your code and my shape and result is:

I change all values but without success !!

Hi @Michael_Pryor

Nice How I can adjust this to my closed curve ?

[René_Corella]

@jdsilvapereira

How I can adjust this to my closed curve ?

you’ll have to put your pentagon on top of all that then trim what’s outside, but you’ll end up with this:

again if the pattern isn’t rotated along or remapped to your boundary

@René_Corella

Clarity is important

repeating myself because nobody here knew you intended to rotate your shapes

here’s an update:
sine_boudary_fill_01_d.gh (68.1 KB)

bake the internalized polygon and reinstate like in the video below to test your rotations

Hi,

I get an error:

I fix with this:

Thanks I will test.
