QElectroTech is an open-source project that maintains a single, highly specialized CAD-style application for electrical engineers, panel builders, automation technicians and anyone who needs to draw professional wiring, schematic and control-circuit documentation. The program provides a drag-and-drop symbol library that covers IEC, IEEE and JIC standards for relays, contactors, PLCs, power supplies, motors, terminals, cables and field-bus components; users place these elements on an unlimited canvas, assign wire numbers, cross-reference coils with contacts, generate terminal strips and automatically produce bill-of-material lists. Projects can be organized into folios, linked through navigation lists, and exported to DXF, PDF, PNG or SVG for insertion into quote packages, instruction manuals or maintenance handbooks. Because the core file format is XML-based and the editor is scriptable, integrators often embed QElectroTech inside larger engineering workflows, feeding parts lists to ERP systems or importing PLC I/O tables generated by automation suites. Hobbyists and educational labs value the portable Windows build that runs without licensing fees, while OEMs appreciate the GPLv2 code that can be forked to add corporate title blocks, language packs or custom symbol sets. QElectroTech is available for free on get.nero.com, where the latest Windows release is delivered through a trusted winget package that supports unattended installation and can be batched alongside other engineering tools.
