librecad/librecad is a cross-platform 2D CAD program that uses Qt and runs on most operating systems. Its purpose is to create and convert precise two-dimensional drawings, and the latest release recorded on GitHub is v2.2.1.6. The implementation language is C++ and the repository has 6515 stars. The repository was created on April 10, 2011, but the changes made in this release are not contained in the given information.
LibreCAD is a drawing tool based on the QCAD Community Edition. It reads DXF and DWG drawings and saves to DXF, DWG, PDF and SVG. Without opening the editor, drawings can be converted from the command line to PDF, PNG, SVG, DWG and DXF, and DWG input/output only works in builds with DWGSUPPORT enabled. It supports points, lines, circles, ellipses, parabolas, hyperbolas and splines as basic shapes. The GUI offers a high degree of user customization and ships with translations into dozens of languages. The README states that LibreCAD is free software under version 2 of the GNU General Public License.
Still, the boundaries are clear. The license field in the repository metadata remains NOASSERTION, so the GPL version 2 claim relies on the README statement. There are no performance comparisons or comparisons against other CAD tools in the given information. The evaluation record retains only a momentum score of 2.8 out of 10, while the freshness, technical and completeness scores are empty. Taking into account that DWG support hinges on a build option as well, it is closer to something to try out with familiar 2D drawing formats than a tool to adopt for professional use right away.
