I have created a mask consisting of evenly spaced rectangles. These structures are to be fully exposed in e-beam lithography, so I need to fill them. I understand that using the layer toolbox to assign some "stipple" is only for visualization and does not actually do any filling?
Do I need to use the fill tool in Utilities? How do I use it? I keep getting an error message saying "no valid layer selected to get fill cell's bounding box from"
Please try to explain simply, as I've only recently started using Klayout :)
