The QElectroTech Portable (often referred to as the "Ready-to-use" version) is a standalone edition of the open-source electrical diagram software that requires no installation. It is designed to run directly from external media, such as a USB flash drive, allowing you to carry your entire electrical CAD environment—including custom symbol libraries and project files—between different workstations without administrative privileges. Core Capabilities of the Portable Feature

Zero-Installation Deployment: Users can simply unzip the provided .7z archive to a removable medium and launch the software immediately.

Full Feature Parity: The portable version includes the complete suite of tools found in the installed version, such as the Diagram Editor for schematics and the Element Editor for creating custom symbols.

Cross-OS Compatibility: Projects created in the portable Windows version are fully compatible with Linux (via AppImage) or Mac versions without any conversion.

Offline Accessibility: Because all necessary binaries and libraries are contained within the folder, it functions perfectly on computers with restricted internet or software installation access. Technical Setup & Usage

Download: Obtain the latest "Ready-to-use" archive (usually in .7z format) from the official QElectroTech Download page.

Extraction: Extract the contents to your desired location, such as a folder on a USB stick.

Execution: On Windows, run the Lancer QET.bat file to start the application with the correct environment variables.

Plugins: To use portable versions of plugins like the Terminal Block Generator, the portable plugin file must be copied directly into the QElectroTech folder and renamed correctly (e.g., qet_tb_generator.exe). Key Benefits for Engineers

Portability of Symbols: Your "User Collection" of custom elements is stored within the portable directory, ensuring you always have access to your proprietary symbol library regardless of which PC you use.

Workspace Consistency: You can maintain a consistent GUI layout and language settings across different hardware.

Safety & Compliance: Ideal for field work where you may need to view or edit documentation on a client's computer where you cannot install new software. Topic: Portable versions of Terminal Block generator plugin

Configuring the "proper paper" size in QElectroTech (QET) Portable is essential for ensuring your electrical diagrams print and export without distortion or cut-offs. Because QET uses a pixel-based grid rather than physical units by default, you must align your Folio properties with standard paper dimensions. 1. Match Pixels to Paper Size

To ensure your workspace matches the paper you intend to print on, use the following pixel dimensions for a standard 96 DPI (dots per inch) resolution: Paper Size Dimensions (mm) Pixels (Width x Height) Recommended Columns/Rows A4 (Standard) 794 x 1122 px 17 columns x 8 rows 1122 x 1587 px 22 columns x 11 rows Letter (US) 215.9 x 279.4 816 x 1055 px 10 cols (105px) x 5 rows (163px) 2. How to Change Folio Size

If your current drawing feels too small or doesn't fit the page, follow these steps to adjust it: Open Folio Properties

: Right-click on your folio (the drawing page) in the project tree and select Folio properties Adjust Dimensions : Go to the Dimensions Columns & Rows

: QET doesn't always have a "Letter" or "A3" preset. You must manually set the number of columns and rows and their individual pixel sizes (e.g., for 17 columns Apply to Project : To make this the default for all future pages, go to Project Properties 3. Printing and Exporting Tips Avoid Scaling Issues

: When printing, the "Page Layout" button in the print preview allows you to select your physical printer's paper size. Ensure this matches your workspace dimensions. Virtual Printers

: For the most reliable results (especially if "Letter" size is missing), use Microsoft Print to PDF

. In the advanced options, you can force the output to a specific paper size. Title Blocks (Cajetines)

: Remember to drag and drop a title block (like "Dina 4" or "Single Logo") that matches your paper size. You can edit these by double-clicking them to fill in the project author, date, and version. QElectroTech

QElectroTech Portable is a free, open-source desktop application designed for creating professional electrical diagrams and schematics, packaged specifically to run from a USB drive or cloud folder without installation. It is part of the broader QElectroTech project, widely used for industrial, automation, and residential electrical design. Key Features

No Installation Required: As a portable app, it leaves no traces on the host computer's registry or file system, making it ideal for engineers and students who switch between workstations.

Extensive Element Library: Includes a vast collection of standardized symbols (IEC, ANSI) for electrical, hydraulic, and pneumatic circuits. Stick with paid software if:

Custom Element Editor: If a specific component is missing, you can design your own integrated symbols using the built-in editor.

Cross-Platform Compatibility: While the portable version is most common for Windows (often distributed via PortableApps.com), the project itself supports Linux and macOS. Best Use Cases

Field Work: Carry your entire design environment and project files on a single USB stick to job sites.

Educational Environments: Students can work on projects in school labs without needing administrative rights to install software.

Documentation: Creating technical manuals or wiring diagrams for machinery and home automation systems. Technical Details

License: Distributed under the GNU/GPL license, meaning it is completely free for both personal and commercial use.

File Formats: Uses XML-based formats for elements (.elmt) and projects (.qet), ensuring your data remains accessible and human-readable.

Multilingual Support: The interface is available in numerous languages, supported by a global community of contributors.

The portable version includes a built-in library (elements/ folder). To add custom symbols:

You can also copy another user’s elements/ folder to reuse their entire library portably.

The trend in software is moving toward web-based tools (like Flux.ai or CircuitLab). However, for industrial electricians and automation engineers, offline reliability is non-negotiable. You cannot have a factory line stop while waiting for a cloud server to respond.

Tools like QElectroTech Portable represent the enduring value of local-first software. It respects your privacy (no telemetry), your mobility (no internet required), and your autonomy (no subscription fees).

As of 2025, QElectroTech continues to evolve with better IEC/ANSI symbol support, improved auto-routing, and a cleaner UI. The portable edition ensures that every time the software improves, you can take that improvement with you—literally in your pocket.

Issue: "Missing DLL files" error on Windows. Solution: You extracted the folder incorrectly. Ensure you copy the entire directory structure, including the bin, lib, and plugins folders. Portable versions rely on these local dependencies because they don't install to System32.

Issue: My custom elements disappeared after moving the USB drive. Solution: You used absolute paths. Go back to Settings → Paths and use relative paths (starting with ./). For example: ./user_elements/my_relays.

Issue: The software is slow when running from a USB 2.0 drive. Solution: USB 2.0 has slow random read speeds. Either upgrade to a USB 3.0/3.1 drive (blue connector) or temporarily copy the QElectroTechPortable folder to the local desktop, run it there (it remains portable because no registry writes), and copy it back when done.

Issue: Antivirus flags the portable .exe. Solution: This is a false positive specific to portable packers (like UPX compression). Portable executables sometimes look suspicious to heuristic scanners. Upload the file to VirusTotal; it will show 0 detections from major vendors. Whitelist the folder.
