You can group together two or more elements. Grouping allows you to move them together without losing the relative distances between them.
1. Select the elements using Shift+click or by dragging the mouse so as to envelop them.Once you do that you'll see the grouping and alignment tool open within the Properties Panel
2. Use the Align tools on the toolbar to align them as you see fit.
3. Click the Group button to join multiple elements together.
Once grouped, you can access each element by clicking twice on them. When you select a group, the Ungroup button becomes available for cancelling the group.
