Adds the event to another explode event group you select.
Adding events to and removing events from an explode group allows you to control when parts animate in the Animation Editor. For example, you may want all the fasteners in an assembly to animate at one time, even though the results of the Automatic Explode command placed them in different explode event groups.
You can also remove events from an explode group with the Remove Event from Explode Group command.
