QCAD - The Open Source 2D CAD

QCAD is a 2D CAD solution for Windows, macOS and Linux. Its core is developed in C++, based on the Qt tool kit. QCAD can be extended through a C++ plugin interface as well as through its very powerful and complete scripting interface (ECMAScript/JavaScript).


QCAD started as version 1 in October 1999 and has since evolved through version 2 (September 2003) and the current version 3 (July 2012 to present).


The QCAD 3 source code is released under the GPLv3 open source license. Script add-ons and C++ plugins are released under their respective licenses.
