Hi Shan,
thanks for your reply.
In fact as u see in the following picture, the remote point is scoped to the center of the face HOWEVER, the moments calculated by selecting remote point are not the same as when selecting 'geometry selection':

2- Just to make sure I well understood your point, if I have a remote point scope to the center of a face, and we apply a rotation to the remote point, the face it's scoped to is going to rotate by the same angles but it's not the case for translational displacement?
