LibreCAD is a cross-platform 2D CAD program. It can read DXF/DWG, and write DXF/DWG/PDF/SVG files. It supports point/line/circle/ellipse/parabola/hyperbola/spline primitives. The GUI is highly customizable, and has dozens of translations.
LibreCAD 
LibreCAD is a 2D CAD drawing tool based on the community edition of QCAD. LibreCAD uses the cross-platform framework Qt, which means it works with most operating systems. The user interface is translated in over 30 languages. https://translate.librecad.org

$ librecad dxf2pdf foo.dxf
