qelectrotech

Create complex industrial electrical diagrams by placing and connecting symbols in QElectroTech’s Qt5 design environment. The program saves diagrams and their component definitions as XML files, keeping project data in a structured, editable format.

It provides separate editors for diagrams, reusable elements, and title blocks, so users can build symbols and presentation layouts alongside their schematics. More than 8,000 included symbols cover common engineering work, while the same tools can also be applied to plumbing, geothermal and air-conditioning plans, layouts, hydraulics, pneumatics, domotics, P&ID drawings, photovoltaic systems, and swimming-pool plumbing.

The software suits electrical engineers, technicians, educators, and students preparing control-circuit documentation or other technical plans. An official collection viewer and a contributor collection viewer help users inspect available symbols, and a Czech translation of the manual supports Czech-speaking readers.

QElectroTech is available for Windows, Mac, and Linux; this Linux release requires snapd and x86_64 (amd64) hardware. The current version is 0.200.1-g5df19f66, and it is open-source software published by laurent trinques in the Education category.
