LibreCAD/LibreCAD
Jul 2011 - May 2016
LibreCAD is a cross-platform 2D CAD program written in C++17. It can read DXF/DWG files and can write DXF/PDF/SVG files. It supports point/line/circle/ellipse/parabola/spline primitives. The user interface is highly customizable, and has dozens of translations.
