Shape Subtract Command in PowerPoint 2013 for Windows

PowerPoint 2013 for Windows lets you change the appearance of merged shapes. Don't get fooled by how easy-to-use this is because the results you can end up with can be seriously impressive. In all, there are 5 options that let you merge shapes, and we have already explored 4 of them. In this tutorial, we'll show you how you can use the Subtract option to subtract one shape from another shape or even shapes. You can see examples of the Subtract 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 Subtract option applied—resulting in a single, cutout shape.

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

The Subtract command is one of Merge Shape commands in PowerPoint 2013 for Windows. Follow these steps to learn more:

1. Select any two or more shapes as shown in Figure 2. Remember that the shape you select first gets subtracted, so it's very important to ascertain what you need to select first! With these shapes selected, access the Drawing Tools Format tab on the Ribbon (highlighted in red within Figure 2).

Note: The Drawing Tools Format tab is a Contextual tab. These 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 Drawing Tools Format tab, click the Merge Shapes button (highlighted in red within Figure 3). This brings up the Merge Shapes drop-down gallery (highlighted in blue within Figure 3).

Do remember these guidelines for any tasks that involve the usage of this command. The Subtract command:

• Retains the first selected shape
• Subtracts overlapping areas of other shapes from first selected shape
• If there is no overlap, the first selected shape is retained. Everything else is removed
• 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 subtracted.
