"Copy" copies the selected object(s) onto a 3D clipboard. The contents of the clipboard can then be "pasted" back into the Ez3d scene, into any OpenInventor-based application.
The 3D clipboard can only contain one object at any time. You can use "Edit - Show Clipboard" to view the contents of the clipboard. The clipboard contents don't change until you do a "Cut" or "Copy" again.
Hint: If you are going to paste the selection back to the scene to make an identical copy, use "Duplicate" rather than "Copy" and "Paste". It is not only easier, but also memory-efficient, because only one copy of the geometry is maintained in the system's memory. This is particularly relevant for scenes with several identical geometries (Example: a city).
