There are T-nodes for four different directions. For each direction, there are then four variants. These variants determine the flow of the connections.
T-nodes can also be displayed as points.
Overview of the main dialog elements:
1st target <direction>, 2nd target <direction>:
The second target (starting from the connecting point withoungt a designation) is always indicated by the diagonal line. Starting from connecting point 1 or 2, the target is always the point without a designation. Here you specify the desired variant by selecting the corresponding option.
Select this check box if you want the T-node to be drawn as a connection point.
If you selected the With target specification or as point option in the dialog Settings: Connection symbols, the last setting made will be saved, and will be used by default the next time you insert a connection symbol.
