About FreeCAD
FreeCAD is a parametric 3D modeler that enables developers and engineers to design and create engineering projects through computer-aided design. It supports parametric modeling, which allows users to modify designs by adjusting parameters rather than recreating geometry from scratch. The tool runs on Linux, Windows, macOS and Unix systems, making it accessible across different platforms. FreeCAD is developed as free and open source software under the GNU Library General Public License, version 2.0 or later. The application is built using C++ and Python, allowing both compiled performance and extensibility through scripting.
As an open source project, FreeCAD provides a foundation for users who need CAD functionality without licensing costs. The combination of parametric design capabilities and cross-platform support makes it suitable for professionals and hobbyists working on mechanical design, architecture, and other engineering disciplines. Being open source under the LGPL, users can inspect the source code, modify it for their needs, and contribute improvements back to the project.
