Ok, then he could draw it all on the schematic layer. It only becomes problematic when you have a circuit board with some parts and spade lug blocks on there to which loose wiring is to be connected that includes runs from one place on the PCB to another. > There are some useful symbols for power systems designed by Jacek > Plucinski here: > > http://jacek-tools.110mb.com/ > Excellent.

In Eagle you can draw on a lot of other layers, for example on the symbol layer. That is very handy if, for example, you want to show fiber-optic signal flow on a schematic which isn't really part of the circuit board. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
