   In this example, the ceiling height of the drawings is set to 10:0. Since both Model Link symbols are placed at a height of 5:0 each, the lower Model link symbol adds a height of 10:0 to every cable routed through it, and the Model Link symbol in the upper floor level does not need to add any length to cables.

   The label "Level 1,R1,CSS1" appears next to the link matrix symbol in the drawing.
