FreeCAD is an open source CAD application that has as its main objective the mechanical development and the industrial design.
This is helped by the modular design that allows a lot of customization to be used in others applications.
FreeCAD is written in Python, and if you know Python you can extend it and automate many of the daily tasks you perform. The open source application can import and export many common formats files for 3D objects. Its modular architecture makes it very easy to extend its core functionality with various plug-ins.
FreeCAD has many options built into its graphical interface. Let's briefly mention the sketcher and renderer as well as a feature simulations robot.
FreeCAD is under active development and its source code hosted on GitHub is available as open source software under permission LGPL.
