I am trying to run a motion analysis study on an assembly. I have assigned mass and centre of gravity but I can't find how can I assign moment of inertia. Any help would be appreciated.
SW calculates the I values both from the origin and the center of mass. If you want to change the I then you can move the assembly within the coordinate system to match where you want it to be.
Thanks for the reply. I want to assign I values from centre of mass. I have modelled a simple representation of the actual assembly for use in motion analysis. Any idea ?
I guess I just don't understand how you would _assign_ the moment of inertia. Isn't that a result of the material density and geometry of the object relative to the axis? If you want to manipulate I you have to vary the geometry.

I expected the inertia to be on the same interface as CG and mass but (I am using SW2011) when i choose the option of assigned mass properties in mass properties dialog box, only mass and centre of gravity options are there.
