    """Defines a point for moment summations.

    APDL Command: SPOINT

    Parameters
    ----------
    node
        Node number of the desired point.  If zero, use X,Y,Z to describe
        point.

    x, y, z
        Global Cartesian coordinates of the desired summation point.  Used
        if NODE is 0.  Defaults to (0,0,0).

    Notes
    -----
    Defines a point (any point other than the origin) about which the
    tabular moment summations are computed [NFORCE, FSUM].  If force
    summations are desired in other than the global Cartesian directions, a
    node number must be specified on the NODE field, and the desired
    coordinate system must be activated with RSYS.
