how to draw single pipe flow and return in netsys

Hi James,

The major thing to bear in mind is that when entering the junctions between the Flow/Return twin pipe and the separate Flow and Return pipes, the separate Flow and Return pipes should be connected into the end of the Flow/Return twin pipe at the exact same point. The image below should help to illustrate this.

Please also note that your system Marker must also be placed on a Flow/Return twin pipe.
