Copying Objects from Existing Diagrams
In a diagram corresponding to a partial view of the information system, you can reuse elements from a more general diagram useful in this new perspective. You can then create the additional objects that you need to obtain the level of detail required.
For example you can copy objects of an Overview created by IS Management and paste them in an Environment Diagram of one of the described applications.
Select and copy for example the sites, applications and databases you want and paste them in the target diagram.
This operation also allows you to recover previously defined links and formatting.
You can also use multiple selection of objects:

Holding down the <Shift> key, click successively on the objects you need.
