insert one more box in the unit cell without array the whole pattern.

Hi
I got a question here about how to use ruby to draw a box in the unit.cell with out being arrayed.
Wrong layout.

Correct layout (desired)

Thanks you.

Hi Mattseng,

If I understand your problem correctly, you want to create a single instance of a cell containing a shape on layer 10 and an array instance of a cell containing shapes on other layers.

You cannot use the same cell for that (unit cell). You'll have to create a new unit cell, place a shape on layer 10 (@layer_index3) and instantiate that cell once (without the array specification).
