SysML Parametrics Toolbox

When you are constructing SysML models, you can populate the SysML Parametric diagrams with constraint blocks, using the icons on the SysML Parametrics pages of the Diagram Toolbox.

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

Hide the frame by right-clicking on the diagram and selecting the Hide Diagram Frame context menu option
Make the frame selectable to move or resize it, by right-clicking on it and selecting the Selectable context menu option
Create Ports and Parts on the frame and create connectors between them

SysML Parametrics Objects




SysML Parametrics

Constraint Property

Instantiates a Constraint Block for use in a Parametric diagram.



Defines a SysML property typed by a DataType, ValueType or Block.


SysML Parametrics Extensions

Objective Function

Defines a SysML Constraint Block for use as an objective function to evaluate Measures of Effectiveness (MOEs).


Measure of Effectiveness

Defines a SysML property for use as a Measure of Effectiveness (MOE).


SysML Block Internal


Describes the decomposition of a SysML Block in the context of its whole using instances of reusable SysML Blocks.


Connector Property

Creates an instance of an Association Block.


Distributed Property

Creates a stereotype of Property, to apply a probability distribution to the values of the property.


Flow Property

Creates a single kind of Flow element that can flow to or from a block.


Participant Property

Creates the end of a connector owned by an Association Block.


SysML Block Internal Relationships


Establishes a traceable relationship describing how one element is dependant upon another.


Item Flow

Specifies the items that flow across a connector in an interaction point. Used in the same way as UML Information Flows.

See Using Information Flows



Establishes Communication links between parts. (See also: Connector.)


Binding Connector

Establishes a connection between two Parts in a system decomposition.


SysML Patterns

Constraint Block

A pattern that creates a typical Constraint property that owns two Parts.
