If you want to use the layout template in another diagram (usually the Composite Structure diagram), the following conditions must be met beforehand:

  • The Part must be typed by the Class or subtype of Class in the Composite Structure diagram.
  • The appearance of the Part type Class or subtype of Class must be defined in the Class diagram.
  • That Class diagram must be set as the layout template.

You can apply layout templates directly from the diagram toolbar or shape's shortcut menu by using the Apply Template command. This command provides different suggestions in the following situations:
