SysML Plugin 19.0 LTR Documentation

The layout templates functionality, which is driven by <<layoutTemplate>> stereotype, assists you in creating well-formed diagrams. It allows you to define Class appearance once, and reuse it later when creating Parts typed by that Class and Ports in different diagrams. Parts and their Ports are represented identically as part's type Class whose layout and style is defined in the layout template diagram. Often, Port position reflects its physical location in the system, so it is beneficial to maintain the same appearance of Parts, layout, and style of Ports throughout the whole model. In the figure below, the appearance of the Modem Card Block is the same in two different diagrams, SysML Block Defiition diagram and SysML Internal Block diagram

Additional information

You can reuse layout templates in other projects by exporting packages to new projects.
