FreeCAD 0.20.2

FreeCAD is a powerful 3D CAD modeler that is perfect for graphic design. It is a free and open-source software that is widely used in mechanical engineering product design, but it can also be applied in other fields such as architecture and electrical engineering. The best part about FreeCAD is that it can be customized and improved upon by its dedicated community using the Python programming language.

One of the standout features of FreeCAD is its complete Open CASCADE Technology-based geometry kernel, which allows for complex 3D manipulations on various shape types. This means that you are not limited to preset shapes, and you can create unique designs. The program also offers a full parametric model, allowing the shape of the 3D objects to depend on tweaked properties or other objects.

FreeCAD supports plugin extensions and different modules, which can be added through scripts to enhance its functionality. Importing and exporting to standard CAD formats is easy, although it may not cover full support for all formats. If you prefer working with 2D shapes, FreeCAD's Sketcher tool allows you to draw geometrical shapes that can serve as bases for your 3D objects.

In addition to its design capabilities, FreeCAD also offers a robot simulation module that allows you to test robot movements within your design. It also provides various features for rendering, architecture, and mechanical path machining, making it a comprehensive tool for technical design.

FreeCAD is a multi-platform program with a user-friendly GUI. It also supports command line usage and allows you to use Python scripts for processing actions. Its versatility and flexibility make it a highly recommended CAD modeler software.
