Creating a fulfill relationship (MBRE profile)
The Fulfill relationship is a PTC proprietary relationship that is available only when the MBRE Profile has been added to a model.
You can create Fulfill relationships on an MBRE Traceability Diagram or through a Modeler pane:
• On an MBRE Traceability Diagram you can create a Fulfill relationship only from an Activity, Actor, Block, Class or Use Case to a Use Case.
• Through a Modeler pane you can create a Fulfill relationship from any item to a Use Case.
* 
When you add a Fulfill relationship to an item, Modeler applies the «UseCaseRelated» stereotype to that item. On the UseCaseRelated tab of the item's Property Pages, the fulfilledBy and fulfills tag definitions show how that item is linked to other items through Fulfill relationships.
To create a fulfill relationship on an MBRE traceability diagram:
1. If you have not done so already, add the items you want to link to the MBRE Traceability Diagram. See Adding items to an MBRE traceability diagram (MBRE profile).
2. On the diagram's toolbar, click the Fulfill button.
3. Click the Activity, Actor, Block, Class or Use Case that fulfills the Use Case, and then click the Use Case that is fulfilled.
4. Type the name of the Constrain relationship, and then press the Enter key.
To create a fulfill relationship through a Modeler pane:
1. Right-click the item that fulfills the Use Case, point to Links, point to Traceability, and then click Fulfills.

Alternatively,
