To add a net segment, use **Add→Net**. There are two modes for adding nets: normal mode, and magnetic mode (the default). To switch between them, use **Options→Toggle Magnetic Net**. | To add a net segment, use **Add→Net**. There are two modes for adding nets: normal mode, and magnetic mode (the default).

When you connect a net to a bus, a "bus ripper" symbol is automatically inserted. This allows two nets to be attached to the same point on a bus from opposite sides without shorting together. | When you connect a net to a bus, a "bus ripper" symbol is automatically inserted.
