You might want to have a look at the net inspector dialog. I needed a similar functionality a while go to get a design job done, so I rewrote the net inspector dialog to be non-modal and updating the trace lengths in real- time as they are being placed (after dragging, not during dragging). Perhaps it could give you some ideas. Best regards, Oleg Endo -- You received this message because you are subscribed to the Google Groups "KiCad Developers" group.
