UML Designer User's Guide

Diagram synchronization

UML Designer automatically keeps each diagram synchronized with its underlying model. The diagram is updated if an element is deleted or changed, or if certain properties are changed (for example, the types of message parameters shown on a class figure). You can also force a resynchronization at any time by selecting Refresh Browser from the Diagram menu.

If you make changes to a model element while editing a diagram, your changes are immediately committed to the underlying model, even if you do not save the diagram. To undo changes to a model element, load the previous edition of the element (see Loading elements for more information). Changes that affect only the visual properties of a diagram (such as figure placement, fonts, and colors) are saved only when you save the diagram. (If you make any such changes, UML Designer prompts you to save the diagram when you close it.)

Note:The appearance of a diagram can change if you change display properties (such as fonts) in the system settings, or if you change an aspect of an element that affects how it appears (such as the length of its name). When this happens, the diagrammers attempt to readjust the diagram appropriately to accommodate the changes. In some cases, some connector figures may appear to become unconnected to their endpoint node figures. If this happens, just drag any loose endpoints to the correct locations.

Missing objects

When you open a diagram, the figures are checked against the underlying model elements. If an element has been deleted or moved, its figure indicates a missing object:
