Interconnection view

From the root Usage, two elements can be displayed in the Interconnection view diagram:

From compartment of Usage part, three elements can be displayed in the Interconnection view diagram:

The following Relationship can be displayed in the General view diagram:

User can create element from the background of the diagram from a simple click that displays toolbar. In this toolbar, element creation tool are grouped by type in tool section according to their type. User can expand the tool section and then user can click on the desired creation tool

User can also create element in other element. User just clicks on the element to display the toolbar and then click on the desired creation tool.

All created element are collapsed by default, it means that if a node with compartment is created, compartment are hidden.

If node contains compartment, user can add element in the desired compartment by clicking in the compartment and display the toolbar.

An other way is to click on the parent node header of the compartment. A toolbar will be display and the user can click on the desired creation tool, new element will be created in the appropriate compartment.

User can only delete a graphical element from the diagram without removing it from the model. User should just click on Delete from diagram button in the palette.

User can also remove element from model (and so from diagram) by clicking on Delete from model button in the palette.

A confirmation dialog appears when an element is deleted via the Delete from model tool in the palette or via the Model Explorer. This behavior can be disabled by checking the "Disable this confirmation dialog" checkbox in the dialog.

Relationship Edges can be created between Nodes whose types match the Edge’s source and target types.

If no edge creation is authorized with a given target, the target node appears faded.

When user try to create an edge, user clicks first on the source element to display arrow border.

Then user clicks on one of these arrows and stay click until the target. User can see the feedback of the edge and the target node is highlighted.

After releasing the click, a pop-up appears and displays all possible kind of edge to create. If only one kind of edge is possible, the edge is directly create without opening the pop-up.

it’s not possible for now to create an Edge between two Edges or between an Edge and a Node.

Users can reconnect Edges by clicking on the source or target end of the Edge to reconnect, and drag and drop it on a new element.

If the new source or the new target isn’t allowed for reconnection, these one will be faded.

To delete relationship from model, user should click on the edge and click on the delete button.

Remember that relationship edge are always synchronized, it’s not possible to only delete relationship edge from diagram.

Containment relationShip isn’t deletable from the diagram. Other relationship can be deletable from the diagram.

Keywords on Nodes and Edges are displayed on the first separate line of the label. For example Definition nodes will be prefixed with "part def" and Usage node with "part".

After the keyword, the label can be the simple name of the element, or more complex in some specific cases. Indeed, For example, subset of the SysML v2 textual syntax is supported to describe some element. For simple Definition element, the label will display the keyword "part def" and its declared name. For elements using specialization, the label will display the kind of the specilalization. For example, if a Batmobile is a subclassification of Vehicle, its label will display the key word "part def" and then "Batmobile :> Vehicle" to show its specalization toward Vehicle.

If Usage element is given by relationship with multiplicity, the multiplicity value (upper and lower bound) is specified between bracket in the label, just before the specialization. For example, for a Batmobile which contained 4 Wheel by using the Usage wheels then the label will be composed of the keyword "part" followed by the name wheels[4] : Wheel which described the Usage wheels with multiplicity 4 defined by the Definition Wheel.

For element with compartment node (with list layout), the label of compartment node will be displayed in italic and it will only contained a simple name.

No label is defined on edges except in two cases :

Element labels can be edited in the following ways:

With direct edit, user can’t change the keyword but user can change the name. If it’s a simple label, he can rename the element. If user modify the multiplicity defined in the label then the multiplicity of the relationship is changed in the model. User can alos set/change the specialization of a given element.

Explore further by referring to the following how-tos for direct edit action

Label of edges and compartments node can’t be edited.

After user selected some elements, a simplified toolbar is displayed.

User can still used basic tools such as :

A new tool section appears in this toolbar. Many tools acting on selected elements layout can be found in this tool section :

In addition to toolbar actions, some actions can be execute with shortcuts.

Indeed, after user selected some elements, user can press the key "Del" to remove all selected elements.

User can also move all selected element on the diagram without changing its graphical or semantic parent.
