You can move around an object in relation to other objects by using the Arrange tool, which can be found on the Toolbar.
Click the object that you would like to arrange, then click “Arrange.”
From the arrange menu, you’ll be able to move the object forward, all the way to the front, backward, or all the way to the back.
You’ll also be able to flip the object vertically or horizontally using Flip.
Align and Distribute will be inactive unless you have multiple objects selected.
Arranging multiple objects
Align will only activate when you have two or more objects selected and allows you to align your objects quickly without having to rely on guidance lines.
Distribute will only activate when you have three or more objects selected and allows you to disperse your objects with equal space between them across your sheet.
