LibreCAD

Overview

LibreCAD originated as a fork of QCad’s community edition, created after a licensing dispute led developer Ries van Twisk to fork the codebase in 2010 and rename the project. Unlike QCad, which offers both a proprietary professional edition and a GPL community edition, LibreCAD is developed entirely as free and open source software under the GPL license, with no paid tier.

The project is built on Qt, giving it a consistent, native-feeling interface across Linux, Windows, and macOS. It deliberately focuses on 2D drafting rather than attempting to compete with full parametric 3D CAD applications, positioning it as a direct, lightweight alternative to the 2D drafting side of AutoCAD.

Key Features

• 2D vector drafting — Precision line, arc, and polyline drawing tools for technical drawings
• Layer management — Organize drawing elements across named layers, similar to AutoCAD’s layer system
• DXF file support — Native read/write support for the DXF interchange format used across CAD tools
• Extensive command-line input — Keyboard-driven command entry for fast, precise drafting, familiar to AutoCAD users
• Customizable toolbars and shortcuts — Interface layout can be adapted to match existing drafting habits
• Cross-platform Qt interface — Consistent native look across Linux, Windows, and macOS

Use Cases

• Technical drafting — 2D floor plans, schematics, and mechanical drawings
• Education — Teaching CAD fundamentals without licensing costs
• Hobbyist and small-shop drafting — Simple 2D drawings for personal or small-business projects
• DXF file editing — Opening, modifying, and exporting drawings shared in DXF format from other CAD tools

Who It’s For

LibreCAD is suited to users who need straightforward 2D technical drafting without the cost or complexity of a full parametric 3D CAD suite. It’s a common choice for students, hobbyists, and small drafting shops that primarily work in 2D and want DXF compatibility with AutoCAD-based workflows elsewhere.
