# AnySeg Query..

Hi,
I am a little confused about the Inertial properites of the segment.
These Intertias [Jii=(Ixx,Iyy,Izz)] should be in the segment co-ordinate
system or they can be in global co-ordinate system?? And segment co-ordinate
system is defined as Arel !!

oops… not Arel, I meant Axes0 in AnySeg definition.

Hello Prabhav

Yes you are right that the inertial properties are defined in the
local coordinate system. The Axis0 describes the initial orientation
of the segment. I will suggest that you try to make a small model with
one segment and then orient it as you want it and type in some
inertial properties and you will easily be able to see how it works.
