Update One-Line Diagram

Use the Update One-Line Diagram command to update your one-line diagram to reflect any changes to your design.

Generally, the one-line diagram is updated automatically as you modify your design. Use this command if changes were made on a different drawing in the project, or when you need to be sure the one-line diagram reflects the latest changes.

To update the one-line diagram, go to
Ribbon: DM Electrical→One-Line Diagram→  Update One-Line Diagram
Pulldown Menu: DM Electrical→One-Line Diagram→Update

This command will update:

  • all of the labels on the one-line diagram;
  • any connections between devices, removing feeders that no longer exist and adding ones that are missing;
  • all of the layers, colors, and text styles to match your current customization settings.
