However, AutoCAD offers you several tools for drawing this box much more easily. Two of these tools are the relative Cartesian and the relative polar coordinate systems. When you’re drawing lines, these coordinate systems use a set of new points based on the last point designated, rather than on the 0,0 point of the drawing area. They’re called relative systems because the coordinates used are relative to the last point specified. If the first point of a line is located at the coordinate 4,6, and you want the line to extend 8 units to the right, the coordinate that is relative to the first point is 8,0 (8 units in the positive x direction and 0 units in the positive y direction), whereas the actual—or absolute—coordinate of the second point is 12,6.
