The Windows screen coordinate system has its origin in the upper left corner of the screen with the positive x-axis pointing to the right and the positive y-axis pointing down. This is the default coordinate system used by Meazure. If you prefer to have the origin of the coordinate system placed somewhere else on the screen, move Point 1 (cursor, crosshair, or window corner) to the desired position and either select the Set Origin item on the View menu or use the shortcut Ctrl+A. To restore the origin to its default position, select Reset Origin from the View menu.

If the origin marker is displayed, it is positioned at the current location of the origin. When the origin is moved, the origin marker moves to the new location.
