Use this function to set CPlane or World coordinates.

CPlane:

This setting constructs the entity in Construction Plane coordinates.

World:

This setting constructs the entity in world coordinates, relative to View 1, top view. World coordinates are always relative to View 1 and represent real model space. The directions of X, Y, and Z axes are independent of the current working view. For example, if in View 8, Axionometric view, all three axes will be skewed to the screen.

When you select World from the Edit>System Settings>CPlane/World options, the coordinates system are automatically assigned to world coordinates.
