PowerPoint 2016 for Mac lets you take a bunch of selected shapes and then apply one of the five Merge Shapes options to end up with some amazing results. However, the Intersect option that we are exploring within this tutorial works a little differently than the Combine, Fragment, Subtract, or Union options that we explore in other tutorials. Before we look at how the Intersect option is different, let us understand what it does. The Intersect command works only when all selected shapes overlap each other. If any shapes do not overlap, Shape Intersect causes complete deletion of all shapes.
