QCAD Pro bundles QCAD with additional proprietary tools and plugins, including read and write support for the DWG file format, SVG export, printing a drawing on multiple pages (poster), and support for splines from fit points. QCAD is an application for computer aided drafting in two dimensions (2D). With QCAD, you can create technical drawings such as plans for buildings, interiors, mechanical parts, or schematics and diagrams. QCAD can be easily extended through plugins and its very powerful and complete ECMAScript (JavaScript) interface.
