The user can visually edit the diagrams, change the position of elements on the diagram, their size, etc. Also add elements to the diagram, delete an element from the diagram and more. The user must have appropriate editing rights, respect locks and other rules.
However, it is important to emphasize that the Inforport EA does not and cannot serve as a full-fledged replacement for Enterprise Architect and the editing options are used for quick entry of changes when the EA cannot be used (on the go, on a tablet, etc.).
After saving the diagram, the changes are written to the EA repository.
