<blockquote>LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation is free from our large, dedicated community of users, contributors and developers. You, too, can also get involved!</blockquote>

LibreCAD (originally QCad then CADuntu) is an open-source 2D [[What_is_CAD|CAD]] application.
''From [http://librecad.org LibreCAD's home page]''
+
It is based on Qt, which is a leading cross-platform application and UI development framework.  
  
LibreCAD is QCad ported from Qt3 to Qt4. It was originally called CADuntu. It is currently being ported to Qt5. It is one of the most complete open source 2D CAD programs on the market.
+
LibreCAD can read DXF and DWG files (and others). It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files.
 +
It has layers, blocks, splines, polylines, ellipse tools, advanced tangent line & circle tools, transformation tools, an advanced snapping system and more.
 +
Because LibreCAD focuses on 2D geometry it is fast and lightweight, with an installer of less than 30mb.
  
This is the community site which provides semi-static documentation for [http://librecad.org LibreCAD] users and developers.

Welcome to the LibreCAD Wiki!

Introduction

LibreCAD (originally QCad then CADuntu) is an open-source 2D CAD application. It is based on Qt, which is a leading cross-platform application and UI development framework.

LibreCAD can read DXF and DWG files (and others). It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files. It has layers, blocks, splines, polylines, ellipse tools, advanced tangent line & circle tools, transformation tools, an advanced snapping system and more. Because LibreCAD focuses on 2D geometry it is fast and lightweight, with an installer of less than 30mb.
