shapes3d rotations to maya

im trying to get rotation angles from shapes3d to use them in maya python scripting. as i know, maya uses euler angles and shapes3d can give me them in some order (e.g. RotOrder: ZYZ).

i can change/define the RotationOrder at MEulerRotation, but they are different (e.g. kZYX) i tried different ways, but the rotations always look wrong.

any ideas?

thanks.
