qcad - A feature-rich drafting application

qcad [ options ] [ files ]

QCAD is a free, open source application for Computer Aided Drafting (CAD) in two dimensions (2D). With QCAD you can create, study and alter technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams. QCAD builds upon the Drawing Interchange File Format. Such DXF-files are used by many other professional CAD-systems.

QCAD works on Windows, Mac OS X and Linux. The source code of QCAD is released under the GPL version 3 (GPLv3), a popular Open Source license.
