A group is a saved set of objects that you can select and edit together or separately as needed. Groups provide an easy way to combine drawing elements that you need to manipulate as a unit.
In addition to choosing the objects that will become the members of a group, you can give the group a name and description.
There are several methods for choosing a group, including selecting the group by name or selecting one of the members of the group.
You can modify groups in a number of ways, including changing their membership, modifying their properties, revising the names and descriptions of groups, and removing them from the drawing.
