Creating a function net and creating a failure net both follow the same rationale. You connect a function to another function, or a malfunction to another malfunction respectively, by dragging and dropping:
With the mouse cursor over a function, press the left mouse button and hold it. Outcome: the function is highlighted with a yellow background.
Move the cursor over the function to wich you wish to connect it. Outcome: next to the cursor will appear a rectangle and a plus sign.
Move the cursor to the left and to the right: You will notice that the function´s background becomes yellow either to the left or to the right side. To connect a function with a lower level system element, the background has to light up on the right (facing the function to which it connects).
Release the mouse button.
