NX Assembly Mass Properties: Measuring MOI about Alternate Axes [NX 2406]

I got a great question today about how to use the NX Mass Properties Management tools to examine/estimate/extract the Moment of Inertia of a set of rotating parts in an assembly. This simple example walks through how to use either the Centroidal MoI numbers or the WCS (Work Coordinate System) MoI numbers to extract this value. In this example you'll see that both methods work great for arriving at the same answer. In general, the Centroidal numbers will work great if you're looking at rotation around the centroid with an axis of rotation parallel to one of the global X, Y or Z directions. If the axis of rotation you're examining is not parallel with one of the standard directions, then placing the WCS such that one of its axes is aligned with the axis you care about will do the trick, and give you the values you're after. I hope that all makes sense! Please let me know if you find this useful!
(NOTE: I recorded this video using NX 2406, but everything in the video can be accomplished in any version of NX since NX 1899.)
