Onshape hinge tutorial, assembly and configurations, part 2

Youtube has been suggesting some Onshape tutorials and a couple I have seen involved drawing hinge and I wasn't impressed by the quality of the advice given... So here's my take on how I would approach something it. A hinge is something that you are likely to want different sizes of, so it's a great practical example to show the value of creating a good parametric model. In this second part I go over the process of creating the assembly as well as setting up various assembly configurations, including using configuration variables and checkboxes.
