The label of implied relation provides useful information about actual ports and Connectors. You can define how much of the information should be shown in the label by changing the Label Display Mode in the Symbol Properties dialog. The procedure below describes how to change the label display mode and explains the meaning each of display mode.

To change the label display mode


  1. Right-click the implied relation.
  2. Select Symbol Properties.
  3. In the Symbol Properties dialog, find the Label Display Mode property and select one of the following value:

      • Do Not Display - to hide the label.

      • Compact (default) - to show a short summary in the label of how many actual connectors are underneath.

      • Detailed - to show all names or types of ports on both actual connector ends.

  4. Click OK.

Compact Label Display Mode

It allows you to show a short summary in the label of how many actual connectors are underneath. It also displays names of the first level ports at both connector ends, if actual connectors exist only between two ports. Otherwise, the names will not be shown. The figure below demonstrates the situation, when all labels of implied relations provide a different information despite the same Compact display mode is selected for all of them.


Three labels of the implied relation with Compact display mode which provides different information.


1. The label of the implied relation between Part Property typed by TV Block and diagram frame indicates that only 1 actual connector exists between part and diagram frame because the number is not shown in brackets. The power in and socket 2 names in the label shows the names of the first level ports.
2. The label of the implied relation between Part Properties typed by TV and TV Tuner Blocks indicates that 18 actual connectors exist between those parts. The hdmi name in the label shows the names of the first level ports.
3. The label of the implied relation between Part Property typed by TV Tuner Block and diagram frame indicates that 9 actual connectors exist between part and diagram frame. The names of ports are not displayed in the label because actual connectors (which are underneath of implied relation) have different first level ports at both ends.

Detailed Label Display Mode

It allows you to show all names or types of ports on both actual connector ends. If actual Connectors are between two ports, the label is the same as Compact mode. The figure below demonstrates the situation, when all labels of implied relations provide a different information despite the same Detailed display mode is selected for all of them.

In the figure above, the labels numbered 1. and 2. in the illustration, provide the same information as Compact display mode because actual connectors exist only between two ports. The label between the TV Tuner Block and diagram frame (3.) shows that 8 connectors exist between internet and LAN socket ports and 1 connector between power in and socket 2 ports. It is useful to set the Detailed mode when you want to see all first level port names in the implied relation label (see figure below).
