The Edge properties form

The Edge properties form is used to define edges in the diagram view.

This pane appears when you edit a diagram view and select an edge.

Field	Description
Relation type	Select a relation type to define the relation type of the currently selected edge. The drop-down list shows all available directed relation types.
Role direction	Indicates the direction in which instances of this relation type are traversed. Selected: The edge is traversed from head to tail. The edge label is the role of the relation type. Cleared: The edge is traversed from tail to head. The edge label is the co-role of the relation type.
from	Select the node from which the edge starts. In the drop-down list of nodes, the nodes that match the current type of edge are shown first (under Matching types). Nodes that do not match the current type are shown after the matching types (under All types). It is also indicated if the node is already in the diagram (on diagram). A matching node is (a parent of) the head asset type of the current relation type (when Role direction is selected) or (a parent of) the tail asset type of the relation type (when Role direction is cleared). Selecting a node that is already in the diagram view adds this edge to that node. Selecting a node that is not yet in the diagram view adds this node to the view.
to	Select the node in which the edge ends. You must select an ID from the drop-down list of nodes. The list contains nodes that match the current type of edge. A matching node is (a parent of) the tail asset type of the current relation type (when Role direction is selected) or (a parent of) the head asset type of the relation type (when Role direction is cleared). Selecting a node that is already in the diagram view adds this edge to that node. Selecting a node that is not yet in the diagram view adds this node to the view.
Style	Select the style of the edge. Arrow: An arrow from the outgoing side to the incoming side. The pointer is on the incoming side of the arrow. This is the default setting. Example Business Asset is the selected node. Boxed: The node on the outgoing side is enclosed by the node on the incoming side. Example Business Asset is the selected node. It is boxed by Employee. Boxing: The node on the outgoing side encloses the node on the incoming side. Example Business Asset is the selected node. It is boxing Employee.
Label	Type a label for the edge. If you do not specify a label, either the role or co-role name of the relation type from the operating model is used in both the diagram view and the diagram. If the Role direction check box is selected, the label is the role of the relation. If it is cleared, it uses the co-role.
