Reply To: Create negative polygon pattern

[Miakatt]

Hi Ronald,

The growing polygons example looks promising. I’ve managed to create a polygon (MMI) and waveguide on one layer, grow the polygon on a second layer and do a layer subtraction in KLayout. It’s not a straight forward as PICWriter, but then I’m unable to create polygons in PICwriter, so it’s a small tradeoff.

Thank you for your help.
