When creating assemblies in Inventor, traditionally you would use Constraints until Joints came along. Whenever anything new is introduced into a workflow it can be very disruptive as you are comfortable with your current workflow.
In the following video I will show 2 different methods in putting together the assembly. One with using constraints and the second using joints. You will see that there are significantly less clicks to achieve the same result with joints as there are with constraints.
This will also give a more clear idea of what is involved as the joint function is still deemed a bit of a mystery to some.
