Just started to use klayout and am very impressed. I am used to Silvaco expert and clewin. There is one thing I am missing: circles. Can this be added by using a ruby script? If so, could you provide a little example?
Another nice little feature I miss that is implemented in Expert is the capability to draw in hole mode, i.e. what ever I draw is directly substracted from the shapes I am drawing on. I know this can be done by boolean operations, it is just much quicker.
