Electrical CAD
built for engineers.
Schematic capture, automatic wire colouring, twelve-check verification, PLC I/O, panel layout. Free, native Windows, no strings attached.
Everything an electrical engineer needs
From schematic capture to panel layout, from BOM to live PLC monitoring.
IEC / JIC / IEEE / NFPA symbols
Over 75 built-in symbols across four standards, plus a custom Symbol Builder and DWG block library import.
Automatic wire colouring
Four modes: IEC 60757, DC polarity, AC phase, default. Applied project-wide from wire numbers.
12-check wiring verification
Dangling pins, dead-end wires, duplicate tags, orphan contacts, power/signal shorts, unconnected PLC channels — all caught.
PLC I/O & backplane drawings
Rack / slot / channel configuration. Backplane auto-generation. Live Modbus TCP monitoring.
Panel layout with 2-way sync
3D isometric panel drawing linked to the schematic. Click either side, the other highlights.
Reports that ship
