Attaching existing NOV-5 diagrams as child diagrams for NAF
After you have created the top-level Context (A-0) diagram, you can decompose its Operational Activity by attaching a child, or decomposition, diagram.
The modeling software does not impose a set limit of diagram levels that you can create to reveal the complexity of parent symbols. The child OV-5 diagram can either be created or attached.
1 Right-click the Parent symbol.
2 Select Child Attach.
3 In the Select for Attaching dialog box, in the list of diagrams, find the name of the diagram you want to attach.
You can use the Name, Target, and Type dialog boxes to narrow the list of diagrams to choose from.
4 Select the diagram name; then click Attach.
5 To save the A-0 diagram, click Yes.
The child diagram is attached.
After you have attached the child diagrams, you need to populate the diagram and move the ICOM arrows to their correct positions.
