Shape Intersect Command in PowerPoint 2016 for Mac

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.

You can see examples of the Intersect option in play within Figure 1, below. The three examples on the top area of the slide are separate shapes placed over each other. The shapes that you see at the bottom of the slide are the same shapes with the Intersect option applied, resulting in a single shape that essentially is a remnant of the area where all selected shapes intersected (overlapped).

Figure 1: Samples showing use of the Intersect command

You will notice in all the sample shapes shown in Figure 1, above that all the shapes used are around the same size. This is especially true of the two shapes to the right, and this is helpful because we start with a selection of shapes that have large "intersecting" areas.

Let's explore another example, as shown in Figure 2, below:

• The leftmost shapes are varied in size. Above, there's a large doughnut shape with a small teardrop overlaid. Notice that the intersecting area is too small, and the resultant intersected shape below thus retains only that small intersecting area.
• The rightmost shapes comprise the same single doughnut shape, but here you have 4 teardrop shapes above. When all these 5 shapes are selected together, there's no area where all 5 overlap or intersect. Thus, the result below is a shape that has no existence!

Once you finish reading this tutorial, do view the sample presentations embedded on the bottom of this page to see more samples of shapes that use the Intersect command.

Follow these steps to learn more about how to use the Intersect command:

1. Open a presentation in PowerPoint. Insert two or more shapes on your slide and select them as shown in Figure 3. With these shapes selected, click the Shape Format tab on the Ribbon (highlighted in blue within Figure 3).
2. 
   Figure 3: Shape Format tab
Note: The Shape Format tab is a Contextual tab. Contextual tabs are special tabs in the Ribbon that are not visible all the time. They only make an appearance when you are working with a particular slide object which can be edited using special options.
2. Within the Shape Format tab, click the Merge Shapes button (highlighted in red within Figure 4). This brings up the Merge Shapes gallery as shown in Figure 4.

3. Within the Merge Shapes drop-down gallery, click the Intersect option to intersect the selected shapes, as shown in Figure 5.

4. Save your presentation often.

Do remember these guidelines for any tasks that involve the usage of this command. 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
• Removes non-overlapping areas of all selected shapes
• Retains overlapping areas of all selected shapes
• Retains formatting of first selected shape

You will see these guidelines in use within the embedded presentations below (scroll down this page).

The sample presentations below show how we used different shapes placed next to and above each other, and then intersected.
