Copy diagram without duplicating entities?

I want to be able to have a series of diagrams, each one adding new content to the diagram. If I create a diagram, copy and past it, I get duplicated entities, which I don’t want. Can someone recommend a way to do this? It is very important to preserve the layout of the diagram. Thanks.

Hi,

Would it work for you if you had each of the diagrams in its own workspace? This would be really easy then and easily created. Just right-click in the workspace and choose Copy Workspace option. Give the workspace a specific name and add the content needed. Then repeat this with the new workspace, etc…

Regards,

Lukas
