Diagram Panel

The 'Diagram' panel provides a collection of tools for managing the use of diagrams and for manipulating the appearance and presentation of elements in a diagram.

Available Facilities

To activate these facilities, open a diagram in the Diagram View. Some facilities are available even when a diagram is not open.

Click on the icon to save changes to the current diagram.


Click on this icon to reverse the last unsaved and un-reversed change made to the diagram. When working with diagrams, it is quite common for a modeler to make a series of changes and then decide to revert to a previous state of the diagram, using the Undo icon to step back through all the unsaved changes that have been made. For practical purposes, there is no limit to how many consecutive unsaved changes can be undone or redone.


Click on this icon to re-establish the last undone and unsaved change made to the diagram.


Click on the drop-down arrow to display a list of options for selecting, copying and pasting elements on the current diagram.

  • Select All Elements - select every element in the diagram
  • Select Elements by Type - specify an element type and - if appropriate - stereotype, and select all elements of that type in the diagram
  • Copy Selected Element(s) - copy all selected elements to the clipboard
  • Clear Current Selection - clear all selected elements in the diagram
  • Make All Elements Selectable - set all elements in the current diagram to Selectable, so that you can move them around the diagram and perform operations on them (make elements unselectable by right-clicking on them and clicking on the 'Unselectable' option)
  • Paste as Reference - paste elements from the clipboard into the diagram as links to the original elements (the elements being copied from a different diagram)
  • Paste as New - paste elements from the clipboard into the diagram as new elements; the 'Paste Elements as New' dialog displays, on which you change the names of the new elements
  • Paste Image as Element - paste a single image of the copied element(s) and any connectors between them from the clipboard into the current diagram; the image is enclosed within a System Boundary, and the element images cannot be selected or moved within the boundary
  • Autosize Selected Elements - returns the selected element(s) to the default size for the element type, or to the minimum size that can show the element contents; the resizing operates from the center of the element, so that you do not have to reorganize the diagram layout

This Zoom option provides a number of zoom settings that you can apply to your diagram:

  • Clear
  •   50%
  •   60%
  •   75%
  •   80%
  • 100%
  • 150%
  • 200%

When you select a zoom level here, it persists when you close and re-open the diagram.

The 'Clear' option resets the diagram's Zoom level to the default; that is, the Zoom level that the diagram was created at. This option only affects diagrams when the 'Base Zoom' setting from the 'Start > Appearance > Preferences > Preferences > Diagram > Appearance' page is set to a value other than 'None'.
