Measure Inertia Matrix referred to a certain axis System

[camahiahua]

Hi everyone,

Does anybody knows hot to get the inertia matrix of a CATPart but referred to a certain Axis System. I Just can obtain the Inertia Matrix referred to the principal Axis System of the CATPart. This is the code I have been using in order to accoplish this.

Set Document = CATIA.ActiveDocument
Set TheSPAWorkbench = Document.GetWorkbench("SPAWorkbench")
Set Inertias = TheSPAWorkbench.Inertias
Set Inertia = Inertias.Add(MyPart)
Dim Matrix(8)
Inertia.GetInertiaMatrix Matrix

Is there a way to obtain this or I have somehow to do the transformation manually???

Thanks in Advance
