This course teaches you the basics of FreeCAD. The course is meant to serve as a starting point for people with little to no prior experience with FreeCAD or CAD in general. Hopefully you will be able to build on the things you learn here and also apply them to other CAD programs with similar functionality, like Fusion360. FreeCAD is completely free and open source. It works on most relatively modern computers and supports Windows, MAC and Linux. You can get it here.
