A Dummy helper object is a wireframe cube with
a pivot point at its geometric center. It has a name
but no parameters, you can’t mo dify it, and it
doesn’t render. Its only real feature is its pivot,
used as a center for transforms. The wireframe
acts as a reference for transform effects.
The dummy object is used primarily in hierarchical
linkages. For example, you can use a dummy
