I created a PCB in EAGLE Cadsoft but Net names are invisible in PCB layer though all layers are selected to be visible. Any suggestion? (I need names to be shown like the "jp1" on top left corner of PCB layer as in below image)
Net names on tracks is available on Eagle 7.6.2 forward.
If you have an appropriate version of Eagle, you can:
Enable signal names on nets under the Misc button, found under Options > Set from the EAGLE menu.
