To make a shape's styles the default for all new shapes:

Select the shape with the styles you want, and right-click.

On the shortcut menu, click
Set AutoShape Defaults.
If you've created a design for a shape type that you'll be using a lot, consider making it the default design. Then, if you don't want a shape to share the default styles, select the shape and apply other styles manually.
The picture on the left shows you how to set the default.
Tips
- Before setting the default, copy a shape that has the original formatting for the slide (that is, a shape you haven't applied any other styles to), and pull it off the slide. If you decide you want to go back to those original defaults, just apply the default command on this saved shape.
- If you set defaults and then decide you want a different default style for the font, you can set that in the Font dialog box (click Default for new objects). This overrides the default font style you set as part of the shape styles. (If you then go back and reset new defaults for the shape, including font styles, these in turn override the most recent font default.)
