QCAD is compatible with Windows, macOS, and Linux operating systems. The software's source code is distributed under the GPL version 3 (GPLv3), a widely recognized Open Source license. Created with a focus on modularity, extensibility, and portability, QCAD is particularly noted for its user-friendly interface. This makes it an accessible yet robust 2D CAD solution for anyone, regardless of prior CAD experience. Users can quickly engage with QCAD to construct and modify elements such as points, lines, arcs, circles, ellipses, splines, polylines, text, dimensions, hatches, fills, and raster images. The application includes a highly capable ECMAScript (JavaScript) scripting interface, allowing for advanced functionality, along with various effective entity selection tools that enhance the drafting process. Overall, QCAD stands out as an excellent choice for both novices and experienced users looking to create detailed 2D designs.
