When manipulating elements from your project browser, there is sometimes a need to move an element from a package to another. To achieve this, users can select the element via a left click, holding down the button while dragging the element to the target package. Once the mouse button is released, the element is moved to the selected package. It is the same process as moving files using the Windows Explorer.
However when the project contains numerous packages, diagrams and elements, this process can be cumbersome. Hence the easier option is to cut and paste the element from within Enterprise Architect Project Browser : run a right click on the element to move and select Copy/paste > Cut or use the keyboard shortcut Ctrl-X. Then select the target package and run a right click > Copy/paste > paste, or use the keyboard shortcut Ctrl-C.
This hint may sound obvious however users are often unaware of the availability of the cut/paste and copy/paste features in the Project Browser.
