Sometimes we have multicore cable and we want to show source and destination markers on the individual wires of a cable, but we want to show the wires coming together to form the cable. So at that time we have to use “Fan In/Out Source/Destination”.

Inserting Fan In Source

Click Schematic tabInsert Wires/Wire Numbers panelSignal Arrows drop-downFan In Source. Then select the style and orientation for the markers and click OK Select the insertion point on the wire Enter a source code for the marker and optionally a description (also we can modify the wire no. & description later ) Click OK
Note :
Two choices are available. We have two options after entering the source arrow: either we continue with the initial source or we insert the source arrow as well as the destination arrow. It is simpler to insert the destination wires right away because they are close by. You might postpone adding the destination marks if the cables were on a different drawing.
