Boolean diff between a cube and 20.000 cylinders - Computer crashes

Hello Community

I wanted to operate a Boolean Difference between this slat and aprox. 20.000 Cylinders for rendering purposes. But my Computer crashes evertime I select more than 50 Cylinders... Scripting seems no solution. 

this is the script

Any suggestions?

    Hi Florian. 

    Why don't you keep it 2D for the boolean?

    Meaning that you will create a perforated plane surface.

    Then if you need it in 3D for a rendering(?), you can extrude this surface.

    My experience is that doing a lot of 3D booleans is always gonna be heavy, but if so, meshes might be faster to work with.

    Cheers Rasmus

    Rasmus comment is spot on. Also it helps to bake all the circle first. Then split a portion at a time.
