Open source parametric 3D CAD modeler for engineering and makers
FreeCAD is a free, open source parametric 3D modeler for mechanical engineering, product design, architecture (BIM) and 3D printing. It is organized into workbenches for part design, sketching, assemblies, technical drawings, finite element analysis and CAM, and can be fully scripted in Python. Version 1.0, released in 2024, added a built-in assembly workbench and fixes for the topological naming problem.
