SysML Internal Block Toolbox

When you are constructing SysML models, you can populate the Internal Block diagrams using the icons on the 'SysML Block Internal' pages of the Diagram Toolbox.

The Block that owns the Internal Block diagram is automatically represented by a diagram frame enclosing the Internal Block diagram elements. You can:

  • Hide the frame by right-clicking on the diagram and selecting the 'Hide Diagram Frame' option (and show it again by selecting the 'Show Diagram Frame' option); if the diagram frame is shown, the 'Diagram Frame' settings on the 'Start > Workspace > Preferences > Diagram' page will be ignored
  • Make the frame selectable to move or resize it, by right-clicking on it and selecting the 'Selectable' option
  • Create Ports and Parts on the frame and create connectors between them
  • Generate Property elements on the diagram inside the Block frame, based on the Associations that the Block element has on the Block diagram

Access

On the Diagram Toolbox, click on the More tools button and select 'SysML 1.3 | SysML 1.3 Internal Block'.
