Groups

A multi-selection is temporary: click empty canvas and it scatters again. A group makes the relationship permanent. Once elements are grouped they travel together for good, until you decide to ungroup them, so the pieces that make up one part of your diagram stay intact no matter how much you rearrange around them.

Creating a group

Start by selecting the elements you want to bind together, then group them. From that point on, clicking any one member selects the whole group, and dragging it moves every member at once while preserving their relative positions. A captioned shape, a legend, or a cluster that represents a single component all stay glued together as you push the rest of the diagram about.

Working with a group

A group behaves like one element in most of the ways that matter. You can move it, copy and paste it, or delete it as a unit, and the copy keeps the same internal arrangement. This makes groups handy for repeating a piece of layout: build it once, group it, then duplicate the group wherever you need the same arrangement again.

Ungrouping

When you need to get at the individual pieces, ungroup. The elements stay exactly where they are on the canvas but become separate again, free to move, restyle, or regroup differently. Grouping and ungrouping are reversible at any time, so there is no penalty for binding things together early and splitting them later.
