In this article I'll show how to use 3D models in KiCAD from either FreeCAD or OpenSCAD. It is possible even if you use a model from another source. As you remember, in the first article we used OpenSCAD to create 3D model, in the second article we used FreeCAD. Using FreeCAD seems to be much easier (almost like point'n'click), but don't forget about the flexibility of OpenSCAD: in some cases its parametrization functionality can be very useful. Maybe you are the laziest and you prefer using 3D model from the internet. It does not matter, anyway in most cases you have to convert this model to the KiCAD-understandable format. In this article I'll try to describe all important steps of these convertions and add more light to the darkest parts of this process.
