SysML Model Elements Toolbox

When you are constructing SysML models, you can populate the diagrams with Model, Package and View elements using the icons on the 'SysML Model' pages of the Diagram Toolbox.

The SysML Model toolbox includes a page of SysML Common element and relationship icons. You can add this page to all Diagram Toolboxes so that it is always available regardless of what type of diagram you are using; to do this, set the SysML 1.5 Technology to 'Active' ('Specialize > Technologies > Manage : SysML 1.5 : Set Active' ribbon path).

Access

On the Diagram Toolbox, click on to display the 'Find Toolbox Item' dialog and specify 'SysML n.n Model Elements' (whichever version you are using).

SysML Model Element Objects

Item	Description
Model	Creates a Package containing a SysML Model.
Model Library	Creates a Package containing a SysML Model Library.
View	Creates a stereotyped Class that defines a SysML View of a system, from the perspective of a SysML View Point.
View Point	Creates a stereotyped Class that defines a SysML View Point, which specifies the rules and conventions for the construction and use of Views.
Stakeholder	Creates a stereotyped Class that defines a SysML Stakeholder.
Package	Groups model constructs in a single unit of containment.

SysML Model Relationships

Item	Description
Conform	Establishes a conformance dependency of a View to the defining View Point.
Dependency	Establishes a traceable relationship describing how one element is dependant upon another.
Import	Represents a reuse of elements from one model Package in another.
Containment	Graphically displays ownership of one element within a parent one.
Realization	Identifies a design fulfillment of a specification between elements.
Refine	Represents a refinement of one element by another.
Expose	Relates a View to another model element.

SysML Common

Item	Description
Comment	Creates a textual annotation that can be attached to a set of elements of any other type. The attachment is created separately, using a Notelink connector.
Document Artifact	Attaches a linked document to the diagram by associating this element with the document.
Element Group	Creates a textual annotation that indicates how many model elements it is attached to.
Problem	A stereotyped Comment that documents the failure of model elements to satisfy a requirement.
Rationale	A stereotyped Comment that documents the justification for decisions.
Boundary	Defines a conceptual boundary, to visually group logically related elements.
Allocate Partition	A stereotyped Activity Partition that contains elements deemed to be allocated to the classifier of the partition.
Requirement	Specifies the capabilities of the system, or the conditions that it should satisfy.
Allocated	A stereotyped Comment that defines the source element being allocated to the target element in an Allocate relationship.
Allocate	A stereotyped Abstraction that relates model elements to formalize a refinement of behavior, structure, constraints or design expectations. The Allocate relationship points from the element being allocated to the element that is the target of the allocation. The system provides an 'Allocations' search that lists all Allocate abstractions in tabular format, showing the 'To' and 'From' elements. Select the 'Start > Explore > Search > Model' ribbon option, then select 'SysML 1.4' as the Search Category; 'Allocations' defaults as the Search Type. If a SysML Block element has any Allocate relationships to or from elements that are not visible on the same diagram, those elements can be listed in 'AllocatedTo' and 'AllocatedFrom' compartments of the Block element on the diagram. Press Ctrl+Shift+Y to display the 'Compartment Visibility' dialog and select the 'Allocatedto' and/or 'Allocatedfrom' checkboxes. Alternatively, you can list the hidden elements on a linked Note. Create a Note element on the diagram and link it to the visible Block element with a Notelink connector. Right-click on the connector, select the 'Link this Note to an Element feature' option and, on the 'Link note to element feature' dialog, click on the drop-down arrow on the 'Feature Type' field and select 'AllocatedTo' or 'AllocatedFrom'. Click on the OK button; the names of the linked elements are now displayed in the Notes element. (To show both 'To' and 'From' elements, create a separate Note for each type.) For either compartments or Notes, you should save the diagram just before setting up the facility, and possibly reload the diagram to activate the facility. If there are no Allocate relationships, or the related elements are on the diagram, the options are not available.
Containment	Graphically displays ownership of one element within a parent one.
Dependency	Establishes a traceable relationship describing how one element is dependant upon another.
Binding Connector	A stereotyped Connector that establishes a connection between two parts in a system decomposition.
Item Flow	A stereotyped Information Flow that specifies the items that flow across a connector in an interaction point.
