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' option (and show it again by selecting the 'Show Diagram Frame' option)
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

If set to non-selectable, the frame will auto-resize to fit the bounds of the diagram, expanding from its default size but not shrinking smaller.

Note that diagrams showing Diagram Frames applied under release 14.0 or higher of Enterprise Architect will draw the parent object on the diagram when opened in a release prior to release 14.0.

SysML Parametrics Objects

Item	Description
Constraint Property	Instantiates a Constraint Block for use in a Parametric diagram.
Property	Defines a SysML property typed by a DataType, ValueType or Block.

SysML Parametrics Extensions

Item	Description
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

Item	Description
Property	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

Relationship	Description	See also
Dependency	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.	Using Information Flows
Connector	Establishes Communication links between parts.	Connector
Binding Connector	Establishes a connection between two Parts in a system decomposition.
