principal axes of inertia - mass properties

    When I select mass properties for a certian assembly, the coordinate system
    of the principal axes of inertia seems wrongly drawn. The origin gets drawn
    on the center of gravity.
    Shouldn't the axes be aligned (parallel) with the output coordinate system?
    Thank you for your help.

    The axes are aligned with the directions of the principal moments. If
    your section has symmetry with the global coordinate system then the
    csys for the princ. moments will likely line up. But if there is
    little symmetry, i.e., an angle or Z-section, the csys will be skewed.
