C# library to read/write cad files like dxf/dwg.

Python interface to DXF

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.

A CAD application built with Rust — 2D/3D drawing, DWG/DXF support, and GPU-accelerated rendering

QCAD - The Open Source 2D CAD. QCAD is a cross-platform CAD solution for Windows, macOS and Linux. It supports the DXF format and optionally the DWG format (through a proprietary plugin).

IfcPlusPlus is an open source C++ class model, as well as a reader and writer for IFC files in STEP format. Features: Easy and efficient memory management using smart pointers. Parallel reader for very fast parsing on multi-core CPU's. Additionally, there's a simple IFC viewer application, using Qt and OpenSceneGraph. It can be used as starting point for all kinds of applications around the open building model standard IFC.

Simple CAD program

LibreCAD 3 is a next generation 2D CAD application written to be modular, with a core independent from GUI toolkits. Scripting is possible with Lua.
