Signal types & wire colors

A signal type names what a conductor carries and sets its wire color on the canvas and in the PDF. Terminals have a default signal, so wires usually pick theirs up automatically. The built-in industrial set follows common NFPA 79 practice:

• 24VDC (+): blue · 0VDC (−): white with blue tracer · AC line: black · AC neutral: white · Protective earth: green/yellow
• 120VAC control: red · Foreign voltage: orange · Analog, Ethernet and RS-485 have their own colors, and comms signals draw dashed

The automotive types added for the example follow vehicle-harness habits: 12VDC (+) red, GLV Ground black, CAN High yellow and CAN Low green (dashed, like all comms), Shutdown Circuit white with a red tracer, and Digital I/O (12V) light blue. Orange is deliberately not used on the GLV side, because on an EV orange means high voltage.

Create your own from any signal-type dropdown (“New signal type…”) or the Codex.

A net that mixes signal types through shared terminals or strip jumpers is flagged in red, with a one-click “Use for all” to make the whole net match.
