Copying and Pasting Model Links
If you copy a linked nugget, without its modeling node, and paste it into the same stream, the nugget is pasted with a link to the modeling node. The new link has the same model replacement status (see Replacing a model) as the original link.

If you copy and paste a nugget together with its linked modeling node, the link is retained whether the objects are pasted into the same stream or a new stream.

Note: If you copy a linked nugget, without its modeling node, and paste the nugget into a new stream (or into a SuperNode that does not contain the modeling node), the link is broken and only the nugget is pasted.
