One-Time Preview Bounds

The only downside to the previous tip is that you change the setting for all operations to use the stroke width. If you're using the Align palette (Window>Align), there is a quicker way for one-time uses. Use the flyout menu in the Align palette and click on Use Preview Bounds to turn it on when you want to use it and turn it off when you're done. In other words, the Align palette temporarily overrides the Preferences setting.
