QCad is a computer-aided design (CAD) software package for 2D design and drafting. It is available for Linux, Mac OS X, Unix and

Microsoft Windows.The QCad Community Edition, which lacks functionality present in

the full version[1], is released under the GNU General Public License and is not (officially) available for Windows[2], though unofficial

builds do exist. Precompiled packages are available for some Linux platforms, such as Debian, via the distribution's package manager.QCad is developed by RibbonSoft. Development on QCad began in

October 1999, starting with code from CAM Expert. QCad 2, designed to "make QCad more productive, more user friendly, more

flexible and increase its compatibility with other products" began development in May 2002.

Much of the interface and concepts behind use are the same of those of AutoCAD.

QCad uses the AutoCAD DXF file format internally and to save and import files.
