Makes visible any hidden component, such as a surface body or design body in a part or sheet metal document, or a part or subassembly in an assembly document. When working with individual PMI elements, makes visible a selected annotation or dimension in the 3D model graphic window or in the 3D model view being edited.

When you point to a Dimensions or Annotations node at the top level of a Dimensions or Annotations collection, the Show command acts as a gatekeeper for the individual PMI elements in that collection. Individual elements can only be made visible if the node is also set to be shown.
