About

QElectroTech is a free, open source software designed for creating complex industrial electrical diagrams. It supports a wide range of diagram types, including electrical, plumbing, geothermal, air-conditioning, hydraulics, pneumatics, domotic, and photovoltaic systems, among others. With over 8,000 symbols available in the latest version, it allows users to create detailed technical diagrams across various fields. The software is licensed under the GNU/GPL license and is available for Windows, Mac OS, and Linux platforms. Its features include a flexible symbol library and user-friendly tools for creating professional-grade schematics. The software is supported by contributions from industrial companies and engineers, including Soliton Controles Industriais and C-Born Engineering, which assist in development and translation. Additionally, QElectroTech supports DXF export for easier integration with other software.

About

ZapSketch is a browser-based electrical home-run planning tool for electricians, electrical contractors, and estimators. Users can import a floor-plan PDF, sketch walls on a blank sheet, or work from a quick drawing, then place panels, junction boxes, and devices and route circuits and raceways. The application measures run lengths and provides preliminary conductor-sizing, ampacity, voltage-drop, and conduit-fill feedback as the layout changes, using documented NEC 2023 calculation assumptions. Users can review circuit schedules and export marked-up plan PDFs and raceway pull schedules for estimating, review, and field handoff; some export details and unwatermarked reports require Pro. Free standalone voltage-drop, wire-size, and conduit-fill calculators are also available. ZapSketch is a preliminary planning aid, not a replacement for adopted-code review, engineering judgment, or verification of project conditions.

Pros & Cons from Real Users

Pros

  • Excellent cross-referencing system (contacts/coils), easy component creation, and bills of materials that save hours of work.
  • Nothing. I liked nothing about this, but I never got past trying to create a title block, so for me there is NOTHING to like.

Cons

  • The initial learning curve, as drawing measurements are based on pixels.
  • The dev's use of unusual methods to do simple tasks
