There are a number of techniques you can use to manipulate the objects in a vector graphics package.

Layering of objects
Overlapping objects can be placed in front of, or behind, other objects.

Scaling without loss of quality
When an object is scaled it is made bigger or smaller. It can be scaled by an exact percentage or by clicking and dragging on the ‘handles’ on the corner of the object.

Rotating
When a vector drawn graphic is rotated, it will be turned through a number of degrees.

Flipping
A vector drawn graphic can be flipped or reflected horizontally or vertically.
