Go to the slide in which you wish to place an object in Microsoft PowerPoint 2010. On the "Insert" tab, click "Object" under the "Text" group.

Learn how to merge two or more shapes in PowerPoint slide. You can use Combine, Union, Intersect, Subtract, etc. options to make a new shape.

Click "OK." Click and drag on the slide to create the object. Click "Properties" from the Controls section -- or you can right-click and select "Properties" -- and PowerPoint will launch a dialog box.

In PowerPoint 2007 and 2010, AutoShape is on the Home tab in the Drawing group. Hold down the [Shift] key when you insert the AutoShape to force PowerPoint to draw a circle rather than an oval.
