Hello!

I really like the ghs above. I should make some changes to it. Unfortunately, I’m very beginner with the software.

Can I set it to have can have only 14 circle size? 1mm 2mm 3mm… 14mm.

Can I set gaps between the circles? 2mm maybe.

Can it be done to generate the image on a rectangular sheet?

How can I set this 3 things?

I would like to save the created draw in dxf for a cnc punching machine.

Thanks.

From the file names, you are referring to this thread?

Which you posted to yesterday, “4 years later”, but no one has replied there.
Please avoid duplicate threads.

Surely, run the tools, scale the outputs until circle has sizes between 1 and 14, transform double to int using int.

You can add 1 mm to all radiuses so [2 to 15]

Take a bigger circle and remove circles that are not in the rectangle.

Here an example without the concentric circles. It shows you the result

Thanks, its great, I love it!

One more question. I would like to set the number of the circles like on the trollnaci_V1_0.
I try to put on the gh what you send, but I’m a little lost… :smiley:

My tool doesn’t work like that. With an image, a rectangle for the tool it calculates the min radius and max radius with “Min Unit Radius” and “Max Unit Radius”.
So with “Min Unit Radius” = 0.001 in theory you could have 500 x 500 circles and if
“Max Unit Radius” = 0.01 in theory you could have just 50 x 50 = 2500 circles.
Of if you have too much circle. Augment “Min Unit Radius” and “Max Unit Radius” with the square root of the ratio.
What you ask is very dependent on the physic support you use. Let say 1 m x 1 m having an image with 2 mm radius to 15 mm radius circle will lead to a certain number of circles. You can lower the number but it will give you more dark pattern.

I hope it helps.

Its so amateur I know… but how can i save this draw to a dxf file? When I try I got an empty dxf.
When I try to select the circles then i have 0 object…

Thanks

How can i get it to have a spatial effect, like the Mona Lisa before.
