LibreCAD (originally QCad then CADuntu) is an open source 2D [[What_is_CAD|CAD]] application for Windows, Apple and Linux.
+
LibreCAD (originally CADuntu) is a [https://www.gnu.org/licenses/gpl-2.0.html free] and open-source 2D [[What_is_CAD|CAD]] application,
It is based on Qt, which is a leading cross-platform application and UI development framework.  
+
which uses Qt (a cross-platform application framework).
 +
The project started around 2010 as a fork of QCAD 2.0.5.0.
  
LibreCAD can read DWG files (and others) as of the latest [https://sourceforge.net/projects/librecad/files/Windows/NightlyBuilds/ Nightly build]. It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files.
+
Support for reading DWG files was added with [https://sourceforge.net/projects/libdxfrw/ libdxfrw].  
It has layers, blocks, splines, advanced tangent circle & line tools, ellipse tools, polylines, many transformation tools, an advanced snapping system and more.
+
Support for writing MakerCAM SVG files was also added.
Because LibreCAD focuses on 2D geometry it is fast and very lightweight, with an installer of less than 30mb.
+
  
Support and documentation is free from our large, dedicated community of users, contributors and developers.
+
The release of 2.1.0 increased customization of the [[User_Interface|user interface]].
 +
You can now create custom toolbars and menus,
 +
and dramatically change the appearance (among other things).
  
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 CADuntu) is a free and open-source 2D CAD application, which uses Qt (a cross-platform application framework). The project started around 2010 as a fork of QCAD 2.0.5.0.

Support for reading DWG files was added with libdxfrw. Support for writing MakerCAM SVG files was also added.

The release of 2.1.0 increased customization of the user interface. You can now create custom toolbars and menus, and dramatically change the appearance (among other things).

The latest stable release is 2.1.3.
