One of the great new features that SOLIDWORKS has introduced in 2016 to assemblies is the Mate Controller. This is most useful for assemblies that have a lot of different motion you are trying to depict with many degrees of freedom.
With the Mate Controller you can assign different positions for the assembly to meet, SOLIDWORKS will interpolate the components motion between the positions and end up giving you a full range of motion. This allows you to playback, animate, and import that into SOLIDWORKS Motion to create easy animations without using configurations. This is just one of many enhancements in SOLIDWORKS 2016.
