Pattern of dots along the perimeter

[zye22222]

Hi, I need help, please. I need to draw fading dots from largest to smallest. These dots are, for example, 3mm, 2.5mm, 2mm, 1.5mm, 1mm, and the dots 3mm, 2mm, 1mm are in one column, while the dots 2.5mm and 1.5mm are in the second column - 2mm apart. I want to replicate this pattern every 4mm, BUT I want this pattern to follow a contour that includes both straight lines and arcs.

I've tried using brushes, but the dots don't arrange themselves nicely on the arcs, they are unevenly spaced. Does anyone have an idea on how to do this?

These are dots like the ones on the car windshield, fading dots along the perimeter.

example:

kind of brushes did you use? With pattern brushes they would be spaced out evenly, but they could be distorted.

[Doug A Roberts]

What do you brush settings look like for this?

[Monika Gause]

THat's a scatter brush. It won't work. A pattern brush will work, but it will dostort the dots in the curves. But also I don't know how to do this without distorting the dots in the curves.

You may want to try a blend a rasterize and halftone effect.

Nice effect, Ton. Looks good.

[Ton Frederiks]

Thanks Larry, I knew I created something like this before, found it, was in 2017.

[zye22222]

Thank you for the response, I'm having a bit of trouble with implementing your idea.

I will keep trying, maybe it will come in handy for me in the future.

I will describe my problem once again, but a bit more precisely in a new statement.

[Ton Frederiks]

Open the attached PDF in Illustrator to see how it is done.

[Ton Frederiks]

Looks like you did not create a blend between a black and a white object.

[zye22222]

Yes, you are right, I didn't make the transition.

Now I've managed to do it.

Thank you.

If I succeed, I will describe my problem in more detail today.

Have a nice day.

The issue I'm trying to solve is:

I have specific dot pattern transitions, such as:

I need to guide it along the shapes as follows:

If someone has any ideas on how to arrange the dots to make the transitions at the corners smooth...

[Ton Frederiks]

Maybe a path with a blurred stroke with the Rasterize and Halftone Effect does what you want? Limit the stroke with a clipping path. (see attached file)

[zye22222]

it's not good for me but thanks for the tip

[Ton Frederiks]

I hope that you tried to change the stroke size, the amount of blur, the resolution and the radius of the dots.
