Offset an Object
Offsetting creates a new object whose shape parallels the shape of a selected
object. Offsetting a circle or an arc creates a larger or smaller circle or arc,
depending on which side you specify for the offset.
A highly effective drawing technique is to offset objects and then trim or
extend their ends.
