Hi Michael,
I just did a few tests. It is inded different than bounding box. The operatation should produce a cylinder which just fits the largest points of an object, no mater it's shape or how it's rotated. The operation I'm familiar with has an option to set an X, Y or Z as the calculation axis for any given object. Maybe this is a mass calc we dont have yet?
