Can you help me to generate randomly distributed void curved circular shaped voids in a square. the figure below shows an example.

$\begingroup$ Thanks for the idea, I redid this model but I got shifts on the edges. i.stack.imgur.com/DFyx2.jpg $\endgroup$– sadedJul 9 at 16:20

I would call this solution experimental, but it may help you:
The principle behind it is relatively simple, and there are a lot of possibilities to influence the result individually.
First I create a grid and move the single points. The node
Map Range
helps me to clamp values. With the nodeMerge by Distance
I bring further disorder into the structure. Finally, I split the faces so that they can be edited separately:In the next step I move the vertices a bit into the center of each face. To do this, I convert the faces into curves, divide them once, and then select every other point to move it with a slight random value:
Finally, I resample the curve to get a higher resolution and apply the node
Blur Attribute
, which smooths the positions of each curve point for me:Finally, I combine the result with a qudratic shape (
Quadrilateral
), which in this case acts as an outer frame, andFill Curve
creates the desired mesh:

$\begingroup$ Thank you for this solution, if I want to convert this mesh to DXF, I add the Realize Instances node. What are the parameters to set to export this mesh in DXF. $\endgroup$– sadedJul 9 at 17:50

$\begingroup$ @saded To do this, you would just have to apply the Geometry Nodes modifier, and use the DXF format when exporting. $\endgroup$– quellenform ♦Jul 9 at 18:01

$\begingroup$ @saded Wouldn't it also be a possibility for you to use the FBX format? Also, it would be better if you create a new question for it, I think. $\endgroup$– quellenform ♦Jul 9 at 18:23

$\begingroup$ I made changes in the mesh exported to DXF, so the results are fine. Thank you very much Quellenform and Duarte Farrajota Ramos. i.stack.imgur.com/HzR2c.png $\endgroup$– sadedJul 10 at 9:52
