Copy/Paste with CTRL+C and CTRL+V

Using this technique it is possible to create secondary objects for all inline and non-inline elements. To achieve this, user has to select shapes on drawing and copy it to clipboard. Next, user has to paste it into the same or different drawing. If all elements can be created as secondary, user is prompted by dialog message as in the picture below (depends on settings).

If the Secondary button is clicked, all shapes become secondary representations of the copied structure.

Note:
That if it is not possible to create the secondary elements (because of at least one database element missing), the system tries to create a new structure in the database.
