KAD 0.8.2 Description:
KAD is a complete 2D CAD system based on QCad by ribbonsoft. It is suited for both beginners and experienced CAD users. KAD is available under the GNU General Public License, version 2. The KDE adoption is written by Martin Teichmann, who is not related to ribbonsoft (therefore don't blame them for bugs). Until now, KAD can only be considered alpha software, unstable, lacking functionality. For the KDE user interface part that is, as QCad is already a production quality CAD system, the CAD part is actually very stable.
