Introduction
Introduction
FreeCAD is a general purpose Open Source 3D CAD
modeler, aimed directly at mechanical engineering and
product design but also fits in a wider range of uses around
engineering, such as architecture or other engineering
specialties. It is a feature-based parametric modeler with a
modular software architecture which makes it easy to provide
additional functionality without modifying the core system.

Features
1 FreeCAD is multi-platform. It runs and behaves exactly
the same way on Windows Linux and Mac OSX
platforms.
2 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.
3 FreeCAD can be imported as a Python module, inside
other applications that can run python scripts, or in a
python console.

Features
4 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.
5 a modular MSI installer allows flexible installations on
Windows systems. Packages for Ubuntu systems are also
maintained.
