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 configuring the appearance of the current diagram.

  • Standard mode - defaults to selected to apply the normal rendition of the diagram; if the current diagram is in 'hand-drawn' or 'white board' mode, select this option to revert to normal display
  • Hand Drawn Mode - display the current diagram in 'hand drawn' mode
  • White Board Mode - display the current diagram in 'white board' mode
  • Theme & Appearance Options - set the theme and appearance options for all diagrams that you review, using the 'Diagram > Themes' page of the 'Preferences' dialog
  • Hide Page Borders (All Diagrams) - hide the printable-page border lines on all diagrams that you review; deselect the option to redisplay the borders (overridden by the 'Hide page borders (current diagram)' setting on the 'Diagram' page of the 'Properties' dialog for the diagram)
  • Show Diagram Property Note - display the diagram property note on the current diagram
  • Set Visible Relationships - display the 'Set Visible Relations' dialog through which you select the relationship connectors to show or hide on the current diagram
  • Show Status Colors (All Diagrams) - display status colors on the status compartment or borders of all status-applied elements on all diagrams you review; deselect to display the elements with the default element fill and shadow colors
  • Configure Status Colors - set the status types and colors, using the 'Status' page of the 'General Types' dialog
  • Reset Local Element Appearance - for selected elements or all elements on the diagram, reset the fill, line and font colors and line width from the locally-set values (via the 'Layout > Style' ribbon panel, for example) to the values defined at the next level (that is, default values set on those elements (the F4 / 'Default Appearance' dialog) or on all elements ('Start > Preferences > Preferences > Diagram > Standard Colors' page)
  • Reset Default Element Appearance - for selected elements or all elements on the diagram, reset the fill, font and line colors and the line width from the F4 / 'Default Appearance' dialog values to the 'Standard Colors' page default; this then updates all diagrams in the model that also display those elements
  • Set Local Appearance as Default - for selected elements or all elements on the diagram, reset the F4 / 'Default Appearance' dialog values of the fill, font and line color and line width to the locally-set values of the selected elements (those elements will change to these colors in any diagram they are on, unless they are not overridden by values set locally or by stereotype)

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

Click on this icon to divide the currently-open diagram into logical areas or partitions using the 'Swimlanes and Matrix' dialog on the diagram.

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'.
