Is that how the contacts of a contactor can refer back to the location of the coil? Obviously each piece which is cross-reference-able needs to be identifiable, so the correct location is discovered. With regards the location cross-references labels, such as XR1, what happens if there are more than two locations? Is it only allowed that two exist? For producing correct electrical netlists, it is important that you assign the same netname to each object. I "think" this will work the way you have drawn, but it deviates quite a lot from what is "normal practice" in gEDA. Usually (when drawing schematics for PCBs / simulations), we label nets with a "netname=..." attribute, or (sometimes), to use a flag symbol like you have, with no refdes= attribute, but instead give it a "net=foo:1" (connecting net "foo" to the whatever is attached to pin 1 of the flag symbol). In order to implement this generically, I imagine your title block could be given some hidden attributes which describe the coordinate ranges inside it which correspond to different grid coordinates. Additionally.. what happens if an item being cross-references spans multiple grid coordinates? Can the choice be random, or does it need to be the one with most of the symbol in it - or top-left one, or some other rule? -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
