Maintaining the aspect ratio of a shape, line, or arrow object

You can specify whether to maintain an object's native size ratio. If the aspect ratio is maintained (locked), and you alter the width of the object, the height will automatically be adjusted to maintain the object's original size ratio. The same is true of the object's width if you alter the height. If the aspect ratio is unlocked, you can alter the width and height independently.

You can select multiple shape, line, or arrow objects to change when necessary.

To maintain the aspect ratio of a shape, line or arrow object:

In the Project Explorer, click the shape, line, or arrow graphic or in the work area, click the shape, line, or arrow object. To select multiple shape, line, or arrow objects, click the first object, then press and hold the CTRL key while you click the other objects.
Click the Position & Size ribbon.
To lock the aspect ratio of the object, click the graphic to display the locked () graphic in the Maintain Ratio graphic. To unlock the aspect ratio of the object, click the graphic to display the unlocked () graphic in the Maintain Ratio graphic.

The aspect ratio is changed.
