You can change the order of builds on a slide. For example, you can make an object move on and off the screen before another object moves onto the screen. You can also make different parts of an object (such as a bullet in a series of bullets) build at different times. (For information about using object parts, see Intermixing Builds of Text, Tables, and Charts.)
In the Build inspector, if the Build Order drawer isn’t open, click More Options. In the Build Order drawer, drag items to reorder them.
Select an object on the slide canvas, and then select an option from the Order pop-up menu in the Build inspector.
