Appendix B: Display Options

The SCE has several display options that can allow for a clearer view of the connections between PACs based on preference.

Connection Stubbing

The connection stubbing feature displays PAC connections as stubs. A stub is a short line terminating with a circle that contains the number of the connection’s destination PAC. When PAC connections overlap, stubs can more clearly identify where a PAC connection terminates.

The following image shows an example of connection stubbing:

Stubbing a Single Connection

To stub a single connection from a result on one PAC to another PAC, right-click on the line that represents the connection and click Toggle Connection State.

Use the same procedure to change a stubbed connection back to a full line.

Stubbing Multiple Connections

To stub multiple connections, select the lines that represent the connections by clicking the lines while holding down the [Ctrl] key. Then click Edit ‣ Stub Selected Connections.

Click Edit ‣ Unstub Selected Connections to change multiple stubbed connections back to full lines.

Stubbing All Connections for a PAC

To stub all incoming or outgoing connections for a particular PAC, right-click the PAC, click Stub, and then click Incoming Connections, Outgoing Connections, or both.

Right-click the PAC and click Unstub to change stubbed connections back to full lines.

Note

This display option only affects existing connections. Any new connections made will not be automatically stubbed.

Connection Marshaling

Connection marshaling combines all lines from a particular PAC that point to a common destination PAC. This option simplifies the display and allows you to select all marshaled connections at once.

The following image shows an example of marshaled connections:
