A simple canvas tool for building electrical diagrams that look professional and are easy to share.
Place components on a canvas and connect them with a click. No drawing skills needed. Just drag, drop, and wire it up.
Choose from a built-in library of electrical components. Panels, breakers, switches, receptacles, and more are ready to use.
Diagrams come out looking professional. Share them with inspectors, general contractors, or your own crew with confidence.
No software to install or update. Open your browser and start drawing. Works on your laptop, tablet, or desktop.
You have a set of architectural plans for a new house and need to map out every circuit. Open Line Diagram, drop in your panel, add your breakers, and lay out the branch circuits room by room. When you are done, you have a clean diagram to hand off to the GC or submit for permit review.
Hand-drawn diagrams are hard to read and impossible to edit. Old diagramming software is expensive and painful to learn. Line Diagram gives you a clean, editable diagram in your browser. Make changes on the fly and share it with anyone who needs it.
A drag-and-drop canvas for building electrical circuit diagrams. Drop in your panel, add the breakers, route the branch circuits. The result: a clean, editable diagram you can hand to a GC, an inspector, or pin to the job folder.
No. There's no command line, no layers, no plotting. Pick a component from the library, drag it onto the canvas, connect it. If you can use a smartphone, you can use Line Diagram.
Yes. Export a clean PDF straight from the app. Labeled, legible, ready to attach to a permit application or email to the inspector.
Yes. The canvas is built for tablet use. Foremen update the as-built in the field at the end of the install day, not back at the office on Friday.
Yes. That's the point. One file goes from the bid to the permit to the as-built. When the GC moves a wall or a foreman re-routes a circuit, you edit the same file instead of redrawing from scratch.
Yes. Standard component symbols built in: panels, breakers, receptacles, lights, motors, transformers. Labeled the way an inspector expects to see them on a single-line diagram.
