I use a system called WSCAD it is written around a access database with libaries of components it also draws the wires automatically when a componets is inserted but only draws vertical to the closest horizontal line or a component pin that is inline it also adds cable numbers automatically and manages PLC's, contactors, relays etc and panel layouts it also prodes a bom wire lists terminal schedules etc it is very good but takes a while to set up the libaries to suit your own tastes -Graham
