Hello everyone, is there any way to get the item in level one by using code block to get 12 items on the list instead of 36?
thanks

Can you explain what you’re after with a sketch? Perhaps simplify the numbers? I’m having a hard time understanding what you want for a result.

Still not entirely clear for me.

Perhaps try defining an extra variable for your stop point. That might help you see what the issue is.

[L,W];
X = 2*W -0.1;
Stop = L-X;
Seq = 0.5..Stop..W;
