A simpler way to draw electrical single-line diagrams
A single-line diagram should communicate the electrical system clearly without turning the drawing process into a software project of its own.
InduDraft gives engineers a focused browser-based editor for placing electrical components, connecting them and preparing a clean drawing for documentation or further CAD work.
There is no software package to install and no account is required to try the editor.
How to create a single-line diagram
- 1
Place electrical components
Choose components from the electrical symbol library and place them on the drawing.
Use components such as transformers, busbars, circuit breakers, fuses, motors and variable-speed drives.
- 2
Build the circuit
Connect the electrical components to show the distribution path through the system.
- 3
Add drawing information
Select components and add tags, descriptions and other available properties.
- 4
Export
Export the completed drawing as PDF or SVG, keep the editable InduDraft file, or create DWG linework for CAD workflows.
Built for clear electrical drawings
Fast placement
Search and place components directly on the drawing instead of assembling diagrams from generic shapes.
Connections
Connect components to show the electrical distribution path clearly.
Tags and properties
Keep equipment tags and available properties attached to the drawing objects.
Browser-based editing
Open the editor and work without installing a dedicated desktop drawing package.
Export options
Export visual documents or hand the drawing over as DWG linework when CAD delivery is required.
For drawing the single-line — without the heavyweight study software
Some electrical engineering platforms combine the single-line diagram with load flow, short-circuit studies, protection coordination and equipment sizing.
InduDraft has a different purpose. It is a lightweight drawing tool for creating and editing the diagram itself.
That makes it useful when the job is to prepare, update or deliver a clear electrical single-line drawing without needing a full power-system analysis package.
Need load flow, short-circuit or protection studies? InduDraft does not currently perform these calculations.
Electrical drawing tools instead of generic shapes
General-purpose diagram applications can be used to sketch almost anything, but electrical single-line drawings have their own components and conventions.
InduDraft provides a dedicated electrical symbol library and drawing workflow, so you can focus on the system you are documenting rather than building your own diagram toolkit.
Generic drawing app
- General shapes
- Manual symbol organisation
- Drawing-specific information often added as text
- Built for many unrelated diagram types
InduDraft
- Electrical component library
- Tags and properties on objects
- Dedicated single-line workflow
- Engineering export options
Use InduDraft for straightforward single-line drawing work
New electrical drawings
Build a clear overview of an electrical distribution system from a blank drawing.
Drawing revisions
Update equipment, tags or connections when an existing electrical drawing changes.
Supplier documentation
Prepare electrical single-line diagrams for packaged equipment and project documentation.
Concept drawings
Quickly communicate the intended electrical structure before detailed engineering is complete.
CAD handover
Create the drawing in InduDraft and export DWG linework when the next workflow requires a CAD file.
Single-line diagram, one-line diagram or SLD?
The terms single-line diagram, one-line diagram and SLD are commonly used for simplified drawings of an electrical power system.
Rather than drawing every conductor individually, the diagram uses a single line and electrical symbols to communicate the main distribution structure and equipment.
InduDraft uses the term “single-line diagram” throughout the product, but the editor is intended for the same general class of electrical drawing.
Familiar electrical drawing conventions
InduDraft's electrical symbols reference familiar IEC drawing conventions.
IEC 60617
InduDraft is not certified or endorsed by this standards organisation. Symbols are maintained as part of InduDraft's own drawing library.
Export the drawing when it is ready
PDFCreate a clean visual document for reviews and project documentation.
SVGExport scalable vector graphics for compatible document and vector workflows.
InduDraft fileKeep the editable drawing with objects and drawing data intact.
DWGCreate AutoCAD 2018-compatible 2D linework for downstream CAD use.
DWG exports contain editable geometry. They are not intelligent electrical CAD objects.
Single-line diagram software questions
What is a single-line diagram?
A single-line diagram is a simplified representation of an electrical power system. It uses standard electrical symbols and a single line to show the main distribution path and major equipment without drawing every individual conductor.
What is SLD software?
SLD software is used to create and maintain electrical single-line diagrams. Depending on the application, it may focus purely on drawing or also include electrical calculations and power-system studies.
Can I draw a single-line diagram online?
Yes. InduDraft's single-line editor runs directly in the browser. You can open the demo without installing software or creating an account.
Does InduDraft perform load flow calculations?
No. InduDraft currently focuses on drawing and editing the single-line diagram. It is not a load-flow, short-circuit or protection-coordination analysis package.
Can I export a single-line diagram to DWG?
Yes. Signed-in users can export AutoCAD 2018-compatible 2D DWG geometry today. It is editable CAD geometry, not intelligent electrical CAD objects. DWG is planned as a Pro feature after the preview period.
Do I need AutoCAD?
No. You can create and edit the drawing directly in InduDraft without AutoCAD. A DWG export is available when the drawing needs to continue into a CAD workflow.
Is a single-line diagram the same as a one-line diagram?
The terms are commonly used for the same type of simplified electrical power-system drawing. “SLD” is an abbreviation for single-line diagram.
Is InduDraft free to try?
Yes. You can open the demo editor and try the drawing workflow without creating an account.
