Removing ratlines from common GND

Estoy haciendo un SHIELD para el ARduino mega, uno los GNDs del arduino al circuito y a los componentes, pero como hago en el esquematico para que no haya ratlines de mas? es decir que si conecto el GND de un componente al lado superior del GND del arduino, no me pida conectarlo de nuevo al GND de la parte de abajo? sin considerar usar un GND copper area. I am doing an Arduino Mega shield where I will put my components, in the schematic I have connected the GND to the same nets and connected all the GNDs from the arduino, but when connecting for exampe a component to the top GND of the Arduino is also a ratline to connect to the GND from the bottom part, how do I do to erase that extra ratline? Considering not using GND copper area

El problema es que tiene tres redes diferentes que deberían ser todas la misma red GND: The problem is that you have three different nets that should all be the same GND net: ![image.png](//image.easyeda.com/pullimage/3dgoP2QciZKhCGm7byI7ZWoIiCshSlquNlUgp9VT.png) ![image.png](//image.easyeda.com/pullimage/M1MFtEHFpbwP60b693NtEGsjdgtt6jQYXxeny0RZ.png) ![image.png](//image.easyeda.com/pullimage/iWi37PO35App3D9yfNiP69A3w78EE6sc8ayqSg0z.png)

Hi This thread is old, but how you fix this problem to make them all the same GND net? it's not quite obvious.... Thanks Mark

@mark.fry, You can connect nets using wires or net names or any mix of the two. If you want a net to be the same everywhere it appears in a schematic then you must either: 1. connect it using the wire tool;  2. give it the same net name by attaching a net label to every separate instance of it. For ground you can use the dedicated ground symbols (the different symbols all represent the same ground so all the ground nets will connect together). For power nets you can use the supply netflags (their names can be edited as desired).

@andyfierman Thanks so much! I just started using EasyEDA, so i feel like i learn a new trick each time. The forum is really helpful. I designed my first circuit board and had it fabricated all in about 3 weeks. m
