You can add splices to electrical routes.
Splices are typically modeled as cylinders containing one or several
connection points. You can add splices by splitting routes, by dragging and dropping
splice components onto routes, and by adding splices from From-To lists. You can also
create connector tables with splices, and add splices to BOMs.
A single splice, with one circuit, must have one CPoint if the two cable
cores have the same direction. When the 2 cables cores are in opposite directions, the
splice must have two CPoints and one RPoint.

A complex splice, with several circuits, must have several CPoints and
RPoints, corresponding to the different circuits.
