COLMAP - Structure-from-Motion and Multi-View Stereo

open Multiple View Geometry library. Basis for 3D computer vision and Structure from Motion.

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.
