QElectroTech

QElectroTech is an open-source electrical diagram editor focusing on industrial automation, HVAC, and general schematic design. Users create or adapt components in a library, then drag them into diagrams for wiring. A flexible workspace supports multiple sheets, references, and real-time connections. The software can generate PDF outputs or image exports for documentation. While it lacks some advanced features of enterprise tools, QElectroTech’s community-driven approach suits small businesses, students, or hobbyists seeking a cost-free solution for accurate electrical drawings and straightforward component reuse.
