NTV-2 Protocol layer definition (UPDM - NAF aliases)
Creation
To create an NTV-2 Protocol Layer Definition:
• Right-click the
Protocol that is to own the NTV-2 Protocol Layer Definition, point to New, point to NAF, and then click NTV-2 Protocol Layer Definition.
If you want the owning element to appear on the diagram: right-click the background of the diagram, point to Populate, and then click Owner.

On an NTV-2 Protocol Layer Definition:
Diagram Elements
For information about the creation and appearance of elements that can be shown on all Product diagrams (Alias, Definition, Information, Metadata, Overlap and Same As elements), see
When you create an NTV-2 Protocol Layer Definition, Modeler does not add the owning Protocol to the diagram.
To show the owning Protocol on the diagram: right-click the background of the diagram, point to Populate, and then click Owner.
To create a Protocol Layer:
• Click the 
Protocol Layer button, and then click the owning Protocol or Protocol Layer. From the Select Type dialog, create or select the Protocol that is the type of the Protocol Layer, or create an untyped Protocol Layer.
Protocol Layer button, and then click the owning Protocol or Protocol Layer. From the Select Type dialog, create or select the Protocol that is the type of the Protocol Layer, or create an untyped Protocol Layer.• From an appropriate Modeler pane, locate the Protocol that you want to use as the type of the Protocol Layer, and then drag that Protocol to free space on the diagram (or to the Protocol if shown) or to the owning Protocol Layer.
If the Protocol that owns the NTV-2 Protocol Layer Definition is not shown on the diagram, create a Protocol Layer on that Protocol by clicking in free space.
The following sections provide information about how an NTV-2 Protocol Layer Definition is used in the model.
