Microsoft Visio has a feature that make wire jumps automagically. You
can even deside if the horisontal wires or the vertical wires should
jump. Arc crossing makes readability of schematics subjectively
better, just like that "solder" dot to explicite show connection even
on T-connections. (If the dot happens automagically, then you know
that there is a connection)

I don't think there is another way but to use wire jumps to
explicitely tell the reader that there is no connection on a crossing.
All other means are implicite and you will have to state the date of
drawing and the state of mind of the drawer in order for the reader to
be 100% shure if there is an X-crossing or a jump when he sees two
cords in a schematic.
