Hi everyone,

Due to fabrication limit I need to cull all the circles that are between 0 and 0.1
I manage to do It with this technique,
https://www.grasshopper3d.com/forum/topics/cull-items-along-a-domain

But I really don’t know why when I plug the data coming out of Cull Pattern give me this result…

I’ve tried different combination of flattening or grafting but no result !

If someone have an idea !

Not behind a pc right now but: Why not simply create a cull pattern from the remapped values <0.1 and then cull the circles with that pattern after they are created.

@HS_Kim solution is better, removing the unused data before feeding into the circles.
