Apache OpenOffice and LibreOffice use the draw:name attribute to provide an access to shapes via "Navigator". They allow the draw:name attribute for 3D-shapes too. But that is currently not included in the specification. My proposal is, to allow the draw:name attribute in 3D-shapes too.
Microsoft Office provides a similar tool "Selection pane", which uses the values from the draw:name attribute. But currently Microsoft Office does not know 3D-shapes in ODF format.
