This is a basic outline of the work flow for SolveSpace. In this video I follow an AutoCAD challenge.
SolveSpace is a free and open source, fully parametric modeler similar to Fusion360, SolidWorks, and FreeCAD. Hopefully this video demonstrates the workflow in SolveSpace and adequately shows the power of such a basic CAD software.

If you have any questions about the software I will do my best to answer them!
