A free, open-source, cross-platform 2D CAD application for reading and editing DXF/DWG files and exporting to PDF/SVG.
LibreCAD is a free, open-source 2D CAD (Computer-Aided Design) application for creating and editing technical drawings. It reads and writes industry-standard DXF and DWG files, supports various geometric primitives, and exports to formats like PDF and SVG. It solves the need for an accessible, cross-platform CAD tool without licensing costs.
Engineers, architects, designers, hobbyists, and students who need a reliable 2D drafting tool for technical drawings, schematics, or plans.
Developers choose LibreCAD because it's a fully-featured, professional-grade CAD program that is completely free and open-source, with strong compatibility with industry-standard formats and a customizable, translated interface.
LibreCAD is a cross-platform 2D CAD program written in C++17. It can read DXF/DWG files and can write DXF/PDF/SVG files. It supports point/line/circle/ellipse/parabola/hyperbola/spline primitives. The user interface is highly customizable, and has dozens of translations.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports reading and writing DXF and DWG files, ensuring seamless collaboration with tools like AutoCAD, as highlighted in the key features.
Built on the Qt framework, it works on Windows, macOS, and Linux with interface translations in over 30 languages, enhancing global usability.
Offers dxf2pdf, dxf2png, and dxf2svg commands for batch conversion, enabling automation without GUI interaction, as demonstrated in the README.
Licensed under GPLv2, allowing full modification, distribution, and community contributions, empowering users with control over their tools.
Requires specific versions of Qt and Boost, and building from source involves multiple steps, which can be a barrier for developers, as noted in the requirements.
Lacks 3D modeling capabilities and advanced features like parametric design, restricting its use for modern CAD workflows that demand more than basic drafting.
macOS builds are not signed by default, requiring manual code signing to avoid 'damaged' errors, adding deployment friction, as documented in the README.
LibreCAD is an open-source alternative to the following products:
AutoCAD is a commercial computer-aided design (CAD) and drafting software application developed by Autodesk. It is used for 2D and 3D design, drafting, modeling, and architectural drawing.
QCAD Professional is a 2D computer-aided design (CAD) application for creating technical drawings, floor plans, and schematics across various industries.
