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.
principal axes of inertia - mass properties

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.
