A form’s global coordinate system is based on the North, East, South, and West coordinates of the ViewCube. When a form is reoriented and has a different relationship with the global coordinate system, it is on the local coordinate system.

When forms are defined by the local coordinate system, the 3D form controls display in orange color. Only the coordinates that change to the local coordinate system display in orange color. For example, if you rotate a cube by 15 degrees, the X and Y arrows display in orange, but the Z arrow remains blue because it still has the same global Z coordinate value.
