3D CAD Modeler Parametric Design Software Printing Windows Mac PC FREECAD

  • FreeCAD is multi-platform. It runs and behaves exactly the same way on Windows and macOS platforms..
  • FreeCAD also runs as a command line application, with low memory footprint. In command line mode, FreeCAD runs without its interface, but with all its geometry tools. It can be, for example, used as server to produce content for other applications..
  • Parametric associative document objects: All objects in a FreeCAD document can be defined by parameters. Those parameters can be modified on the fly, and recomputed anytime. The relationship between objects is also stored, so modifying one object also modifies its dependent objects..
  • Built-in scripting framework: FreeCAD features a built-in Python interpreter, and an API that covers almost any part of the application, the interface, the geometry and the representation of this geometry in the 3D viewer. The interpreter can run single commands up to complex scripts, in fact entire modules can even be programmed completely in Python..
  • User interaction mirroring on the console: Everything the user does in the FreeCAD interface executes Python code, which can be printed on the console and recorded in macros..
