Calculation of moment of inertia in Car

jozef.bucha
Hello everyone,
 
I do not understand why adams car computes moment of inertia in different way than adams view. If i understand correct Adams view as default uses cm marker for both cm position and orientation. According geometry view orients cm marker in such way that only Ixx, Iyy, Izz are there and Ixx>Iyy>Izz. Adams Car uses two markers cm and inertia. cm oriented , but inertia is calculated according inertia marker with is positioned in same place as cm marker, but oriented same as PCS. Why? What is advantage of this?
 
Second question why i have all values same (mass, cm position, Ixx, Iyy, Izz) but Iyz has different sign. I believe that both Adams and Catia are same.
