Figure 43: The QCad application running under KDE.
QCad is a professional level CAD System. With QCad you can construct and change drawings and save them in DXF format which allows you to import/export your drawing into other CAD systems such as AutoCAD. An example of the QCad interface is shown in Figure 43.
The QCad application requires the presence of the Troll Tech Qt Library which underlies the KDE
desktop environment. If you are running Linux it is likely that KDE, and hence the Qt library, is
already installed. If not, more information about the Troll Tech Qt library can be found at
http://www.kde.org/ and http://www.troll.no/.
Further information on the QCad program can be found at http://www.qcad.org.
The XCircuit application, while flexible enough to be used as a generic drawing program, is primarly aimed at the production of publishable-quality electrical circuit schematic diagrams and related figures, see Figure 44.
Further information on the XCircuit application can be found on the author’s web site at http://bach.ece.jhu.edu/~tim/programs/xcircuit/.
