Moment of inertia reference point

I can't really find anywhere what the reference point is for the calculated moment of inertia in OnShape. I'd expect it to be either the origin or the c.o.g. of the assembly.

    I'm not sure where the default position is.

    But you can set a reference point with a mate connector.

    I've looked into it and without a specific reference frame, the moments of inertia are calculated about the center of gravity of the selected instance(s).
