PowerPoint 2011 lets you merge the shapes with its four Combine Shape commands: Combine, Union, Intersect, and Subtract — you can end up with some seriously impressive results. In this tutorial, we’ll show how you can subtract one shape from another. For example, we placed several shapes over one larger heart shape as shown towards the left of the figure shown. With these shapes selected, we could use the Subtract command that is explained later in this tutorial to create a cutout shape, as shown towards the right of the same figure.
Learn how you can create new shapes in PowerPoint 2011 using the Subtract command.
