FreeCAD is an open-source parametric 3D modeler designed to help you create real-life objects of any size. With its parametric modeling capabilities, you can easily modify your design by revisiting your model history and adjusting its parameters.

  • Parametric Modeling: Easily modify designs by changing model parameters.
  • 2D to 3D Conversion: Sketch geometry-constrained 2D shapes and use them as a base for 3D objects.
  • Multi-Platform: Available on Windows, Mac, and Linux.
  • File Compatibility: Reads and writes various open file formats like STEP, IGES, STL, SVG, DXF, OBJ, IFC, and DAE.
  • Customizable and Extensible: Highly customizable and extensible to fit various needs.
  • Diverse Applications: Suitable for product design, mechanical engineering, and architecture.
  • Advanced Tools: Equipped with Finite Element Analysis (FEA) tools, experimental CFD, BIM, Geodata, CAM/CNC workbenches, and a robot simulation module.

FreeCAD is designed to cater to a wide range of users, including hobbyists, programmers, experienced CAD users, students, and teachers. It truly is a Swiss Army knife of general-purpose engineering toolkits.
