The STRETCH Command Select only the porcon of the object to be stretched. If you select the encre object, STRETCH acts like MOVE. Pick a basepoint. This is the locacon from which the object will be stretched. Pick a new posicon for the base point. As you move the screen cursor, the object is stretched or compressed.
