# CircuitDiagramMaker

> CircuitDiagramMaker is browser-based electrical documentation software for wiring diagrams, circuit schematics, single-line diagrams, control panels, and wire harnesses. It offers 480+ electrical and electronic symbols, terminal-aware routing, live engineering schedules, supported-model DC/transient/AC analysis, and PDF, SVG, PNG, DXF, JSON, and CSV outputs. More than 2,000 topology-passing reference diagram pages and 480+ symbol references are available; automated checks are not independent engineering certification.
