The Zero Origin command automatically resets the origin as follows:
In Draft, the drawing grid origin is reset to the drawing sheet (0,0) coordinate.
In profile and sketch, the drawing grid origin is reset to the (0,0) coordinate at the center of the current reference plane.
In synchronous modeling, both the drawing grid and the sketch plane origin are reset to the (0,0,0) coordinate and orientation at the center of the currently locked sketch plane.
Note:
This command is available only when you have locked a sketch plane.
