How to Add Wire Numbers to Schematics in 10 Seconds or Less

Last Updated on by DesignPoint Team

Adding wire numbers to a schematic with standard 2D CAD software can be a tedious, time-consuming and error-prone task – especially if a project is revised before sending it out to production.

Power lines are often numbered differently than other wires, and there might be even more variation based on the type of wire we are looking at, so things can get very complicated very quickly. It’s a lot to keep track of and is often a task we dread. So what’s the alternative?

Since all of my wire styles are setup correctly in the SOLIDWORKS Electrical Wire Styles Manager with an equation, all we need to do is go to the Process tab and click Number new (or renumbered) wires.

See this action in the video below:

From here, we can make any manual changes by double-clicking on a wire and entering a value into the New column.

… or we can (new in SOLIDWORKS Electrical 2017) propagate data from connected objects!

Note: Depending on your standards, this new feature is a HUGE time saver.

In this example, we want to propagate the PLC Channel address to the wire equipotential. As you can see here, all wires have been numbered based on their standard formulas:

Rather than manually overriding each and every wire mark with the PLC Channel address, all we need to do is click on Propagate data to connected objects (also on the Process tab) and select:

  1. The object to copy from
  2. The data to copy
  3. The object to copy to
  4. The associated data to copy to

Then all we need to do is click on OK. Within 5 seconds, we see our result:

So kick back, relax, and enjoy not numbering your wires the hard way ever again. This is just another example of how SOLIDWORKS Electrical takes the pain out of schematic design, allowing us to focus on innovation!
