Bevel direction
Bevels can be inside the object or outside. Outside bevels make objects larger; inside bevels do not change the object size.
To change bevel direction:
1. Select the object (see Selecting objects).
2. Choose the Bevel Tool.
3. If necessary apply a bevel (see Applying a bevel).
4. Click either the Inner or Outer button.
Tip:
 If you have several beveled objects 
 selected, any changes apply to all the bevels.
 If you have several beveled objects
