Coordinate system

 Absolute coordinate system

• In the absolute coordinate system all points are measured from the original (0, 0). They are suited to situation where you know the exact X and Y location of the point you want to place. 
• To enter an absolute coordinate use the formal X, Y where:
• X is the distance and direction along the horizontal axis from the origin (0, 0). Y is the distance and direction along the vertical axis from the origin (0, 0).
