4.5.1.
What are Interconnections?
An
interconnection
is represented by a line that connects the input of a technological function to the output of
a second technological function.
When you delete a technological function, all the associated interconnections are deleted.
When you move a technological function, the course of the associated interconnections is also changed.
If the course of a line cannot be calculated due to lack of space, then only the two ends of the interconnection
are displayed. These are known as
continuation connectors
.
The color of the line changes when you select an interconnection. You can delete a selected interconnection or
view and modify its properties.
