SysML Plugin TWRT Documentation
You can create element groups to more easily manage selected (possibly heterogeneous) model elements. For example, you can group elements associated with a particular model release, elements that have a certain risk level, or requirements that need to be satisfied. New elements can be added to a group and unnecessary ones removed from it any time directly from the element shortcut menu.
