About QElectroTech

A free and open-source application to create electrical diagrams

What's new in 0.100.0

QElectroTech, or QET in short, is a free software to create industrial complex electric diagrams.
But you can also even do plumbing, geothermal, air-conditioning, layout, hydraulics, pneumatics, domotic,
PID, photovoltaic, swiming pool plumbing, ect...!
On last version 0.100 the collection contains over 8000 symbols...
Version 0.100
Compiled from provided commit logs and contributor notes.
Overview
This release (v0.100) collects a large set of new features, UI and editor improvements, element and symbol updates, build and packaging fixes, dependency upgrades, translations, and a broad set of bug fixes and stability improvements. It is intended as a stable, feature-rich stepping stone toward the next major workflows for symbol editing, terminal/strip handling and export improvements.
Highlights / Key Features
- Terminal Strip / Terminal Strip Editor
- New TerminalStripItem type and related editor workflow added.
- Support for drawing and displaying terminal bridges and links in the editor.
- Full editor support (layout preview, save/load into .qet files) and undo support for terminal strip operations.
- New Example Projects
- Several new example projects included, notably photovoltaic (PV) examples to help users getting started with PV designs.
- Improved Export / Print Handling
- Export limits adjusted and better handling of QPainter/printing boundaries to avoid export artefacts and out-of-range errors.
- Export dialog updated to allow larger pixel limits where appropriate.
- Element & Symbol Additions
- New elements and symbols added (including vendor-specific elements and additional sensors/Arduino components).
- Improvements to element import & metadata handling.
- Packaging & Multi-arch Support
- Updated packaging scripts for AppImage, Flatpak, Snap and macOS deployment. Improved aarch64/arm64 support.
Detailed Changes
Editor & UX
- Better handling for rotation, flip and mirror operations in the element editor:
- Primitives and text rotation behavior improved.
- Finer rotation increments and predictable text orientation after flips/rotations.
- Wiring and conductor behavior:
- More robust creation and movement of wires and conductor bundles.
- Improved text attachment and positioning for wires and improved stability while editing complex conductor networks.
- TerminalStrip editor: see Highlights - includes drawing, preview, layout editing, persistent storage in the project file and undo support.
- Element Editor & Symbol Trim/Sort: …
