Line Intersection Jumpers

I regularly have to create drawings with lines representing water pipes that cross over each other but are not connected, and so I manually insert semi-circular 'jumpers' much like for wiring diagrams.  Does anyone know a way of doing this automatically please since it's very time consuming?  I think Autocad has a plug-in that can do this, but I'm not sure if DraftSight has anything similar.  Thanks.
