LibreCAD — Free 2D Editor for Engineers and Designers

Do you know the frustration of needing to quickly make edits to a drawing, but you don't have a licensed AutoCAD at hand? Or when a project budget doesn't allow for purchasing expensive software? This is exactly where LibreCAD comes in — a full-featured open-source 2D editor.

What is this tool?

LibreCAD is a cross-platform computer-aided design (CAD) system written in C++ using the Qt framework. The project originated as a fork of QCAD Community Edition and over 12 years of development has evolved into an independent solution with an active community.

Who is it for:

  • Engineers and designers
  • Architects and designers
  • Technical discipline instructors
  • Students and DIY enthusiasts

Five Reasons to Try LibreCAD

  1. Completely free — the GPLv2 license allows you to freely use, study, and modify the program.

  2. Cross-platform — works on Windows, macOS, and Linux thanks to Qt. In my practice, this is especially valuable when working in mixed teams.

  3. Format support — reads DXF/DWG (via libdxfrw), exports to PDF, PNG, and SVG. For example, for quickly converting a drawing to an image:

librecad dxf2png чертеж.dxf
  1. Multilingual interface — translated into 30+ languages, including Russian.

  2. Active community — forum, IRC channel, and over 100 contributors on GitHub.

Technical Features

The current version (master branch) requires Qt 6.4+, which provides:

  • Improved performance
  • Support for new C++17 standards
  • Modern graphical interface

For legacy projects, branches with Qt 5 and even Qt4 support are available (branch 2.1).

Practical Applications

Real-world cases from my practice:

  • Quick creation of schematics for 3D printing
  • Preparing technical documentation in PDF
  • Converting old DWG files to modern formats
  • Teaching students the fundamentals of design without spending on licenses

How to Get Started

  1. Download the installer for your OS: official website
  2. Study the documentation: user guide
  3. Join the community: forum

LibreCAD is not just a "free AutoCAD." It's a mature solution with:

  • Rich functionality for 2D design
  • Extensive customization options
  • Active development and support

I especially recommend it for:

  • Freelancers who value mobility
  • Educational institutions
  • Companies looking for alternatives to expensive software

Give it a try — LibreCAD might become your primary tool for working with 2D graphics.
