Resizing Objects Manually 
You can manually resize an object.
Note
In Design Manually mode, perspectives are associated with objectives and are automatically resized when resizing objectives either larger or smaller.
You are in either Design Manually or Custom Image mode.
To work with objects and not arrows, make sure the arrow button is off. Or, make sure is not selected.
(Optional) If you want to snap the shapes to a grid, choose .
Click the object to select it, then select a green point on the object and drag the point to a new size.
Caution
Do not choose Auto-Layout mode after changing the size of an object. Auto-Layout organizes diagram objects into a predefined layout and cannot be undone.
