FreeCAD is an open-source, parametric 3D CAD modeling software made primarily to design real-life objects of any size. It is designed to be a platform for product development and mechanical engineering. FreeCAD is available under the LGPL license, with a growing community of enthusiasts and developers expanding its features through workbenches that serve different needs such as architecture or robot simulation. The software supports 3D project creation using traditional sketches and extrusion/revolutions, as well as more advanced operations like sweep or loft tools which can be used in sequence due to its parametric model tree, making modification easy at any stage of the design process. FreeCAD can interact with simulation packages like OpenFOAM or CalculiX for analyzing fluid dynamics or structural mechanics—a valuable tool for professionals looking for free alternatives in the CAD world.
