Ratline

When you layout the track in the PCB, Between Pad and Pad as they have the same net name, a Ratline will be automatically shown among them to reveal that they can be connected with a track.

1. If you want one ratline do not show on the PCB editor, you can deselect the net in the design manager, as below deselect +5V: If you still draw a track in +5V after deselecting, canvas will not display this track and ratline , but it will show a net text with +5V as below.
   Based on this skill， you don't need to lay GND net before copper area in the PCB.
