PowerPoint 2010 lets you change how your shapes merge with its four Combine Shape commands: Combine, Intersect, Subtract, and Union — you can end up with some seriously impressive results. In this tutorial, I’ll show you how you can subtract one shape from another. For example, I placed two shapes over each other — with these shapes selected, I could use the Shape Subtract command that I explain later in this tutorial to create an entirely different, subtracted shape.
Learn how you can subtract shapes in PowerPoint 2010 for Windows using the Shape Subtract command.
