With Creo 7 it is now possible to use Bodies as the Base for a copy geometry.
These Copy geometries will include solid geometry instead of only surfaces, like before Creo 7.
Especially for seasoned users it was always clear, that a copy geometry will never have solid geometry nor change the mass but "just" copy surfaces and / or datums.
Idea is to adapt the model Tree Icon of the Copy Geometry to show if the copy geometry includes bodies (solid geometry) or only surface and / or datums.
The workarround to use the "Contributed Body" Column of the model tree is known but a change in the Model Tree Icon would be preferred
