One-Line Diagram

The One-Line Diagram is a user-friendly interface to create and manage the network database used for schematic network visualization.
One-Line Diagram Toolbars

It is designed to interactively model, monitor, and manage electrical networks as well as execute simulation scenarios and analyze their results in a simple and intuitive manner. Other features include multi-level nesting of sub-systems, multi-color symbols, interfaces for management of switching devices, and a unique multi-dimensional database.

An a large set of new features has been added to the intelligent One-Line Diagram propelling day-to-day system modeling and design tasks to a new level of speed, ease, and accuracy more than ever before.

One-Line Diagram Display


Auto-Build is an automated and powerful tool for creating and editing the one-line diagram. The rule-based design of Auto-Build can significantly reduce the time spent on creating a one-line diagram.

  • Automated creation of a one-line diagram without leaving the equipment toolbar
  • Quick & intuitive One-Line Diagram generation
  • Automatic spacing & alignment rules
  • No need to drag, drop, locate, and connect


Add component information, input data, and study results in one block to view on the one-line diagram. Datablocks are also fully customizable allowing them to be shown, hidden, arranged, and formatted according to the user’s preference. An advantage with using Datablocks is showing properties and results from different studies and displaying this information within the same one-line diagram.

  • Customize input data & study results
  • Display results, tags, and/or properties
  • Define templates & share
  • Automatically apply templates
  • Instant preview of Datablock

Composite Network & Motors

The “Composite Network,” or sub-network allows users to model a portion of their project and represent it as a single element, providing a more simple and organized appearance. The “composite network” can be nested for an unlimited number of sub-networks, allowing for multiple layers in one project.

Customizable Views

  • Unlimited Connections
  • User-Defined Location & Sizing
  • Visualize Properties & Results

Theme Manager

Set different themes for individual one-line diagrams. Themes can be color coded based on standard, voltage level, area, ground, earthing, and grounding by ground switch. The user can also add contouring as an option. This functionality allows the user to place a user-configurable color map behind the one-line diagram. These maps are color coded based on voltage or power flow magnitude.

User-defined result format

  • Display / hide based on:
    • Zoom level
    • Equipment type
    • Equipment state
    • Info annotations
    • Study Results
    • Datablocks
