About Entering 2D Coordinates

Enter absolute coordinate

Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the X and Y axes. If you know the precise X and Y values of the point, you can use absolute coordinates.

Enter relative coordinate

The last point entered is used as a base for relative coordinates and you can use them, if you know the location of a point in relation to the previous point.

Enter polar coordinate

When creating objects, you can use absolute or relative polar coordinates (distance and angle) . The distance and the angle separated by an angle bracket (<) when you use polar coordinates to specify a point.

Absolute polar coordinates are based on the origin.

Relative coordinates are based on the last point entered. If you know the location of a point in relation to the previous point, you can use relative coordinates.
