FreeCAD

FreeCAD is an open-source parametric 3D modeler built to help you design real-world objects of

any size. With parametric modeling, you can easily modify your designs by adjusting parameters

in the model history. FreeCAD is suitable for a wide range of uses, from product design and

mechanical engineering to architecture and 3D printing.

The software allows you to create constrained 2D sketches, which can be used as the basis for more

complex 3D models. It includes tools to adjust dimensions, extract design details, and produce

production-ready technical drawings. FreeCAD is available on Windows, Mac, and Linux, and

supports various file formats like STEP, IGES, STL, SVG, DXF, OBJ, IFC, and more, making it easy to

fit into existing workflows. It also supports customization through Python scripting for those

who want to automate tasks or develop custom features.

FreeCAD offers several specialized workbenches, including tools for Finite Element Analysis

(FEA), Building Information Modeling (BIM), CAM / CNC and robot movement simulation. You can expand its

capabilities with add-ons, plugins, and macros created by the FreeCAD community, which can be

installed directly from the application. This flexibility makes it a practical choice for both

professionals and hobbyists.
