FreeCAD

About

FreeCAD is a versatile and open-source 3D CAD software, primarily designed for creating complex models in various fields such as product design, mechanical engineering, and architecture. It features a parametric modeling system, allowing users to modify designs by adjusting parameters at any stage. FreeCAD supports multiple file formats, including STEP, IGES, STL, and others, making it compatible with various workflows. Its modular architecture allows for plugin extensions, enhancing its functionality with modules like Part Design and Assembly workbenches. FreeCAD offers tools for 3D modeling, finite element analysis (FEA), and CNC machining. It includes workbenches like TechDraw for 2D documentation and FEM for analysis. The software supports Python scripting, enabling automation of tasks and customization of the interface. FreeCAD is available on multiple platforms, including Windows, macOS, and Linux, and is backed by extensive documentation and a vibrant community. Its recent updates include improvements in topological naming and the introduction of an Assembly workbench, enhancing its capabilities for complex assemblies and design workflows.
